Hadith.4899 - It has been narrated from Abu Said al-Khudri that the Messenger of Allah سبحانه وتعالى (peace and blessings be upon him and his family) advised Imam Ali ibn Abi Talib عليه السلام, saying: "O Ali عليه السلام, when the bride enters your house, remove her shoes when she sits, wash her feet, and pour the water from the entrance of your house to the farthest part of your home. If you do this, Allah سبحانه وتعالى will remove seventy thousand kinds of poverty from your house and bring in seventy thousand kinds of blessings. Seventy mercies will descend upon her, fluttering over her head, and their blessings will reach every corner of your house. The bride will be protected from insanity, leprosy, and vitiligo as long as she remains in that house. Prevent the bride, during her first week, from consuming milk, vinegar, coriander, and sour apples. Imam Ali ibn Abi Talib عليه السلام asked: 'O Messenger of Allah سبحانه وتعالى, why should I prevent her from these four things?' He (peace and blessings be upon him and his family) said: 'Because the womb becomes barren and cold from these four things, which affect childbearing. A simple mat in the corner of the house is better than a woman who does not bear children.'" Imam Ali ibn Abi Talib عليه السلام asked: "O Messenger of Allah سبحانه وتعالى, what is the reason for avoiding vinegar?" He (peace and blessings be upon him and his family) said: "If she menstruates while consuming vinegar, she will never attain complete purity. Coriander provokes menstruation in her womb and makes childbirth difficult for her. Sour apples cut off her menstruation and may cause illness for her." Then he (peace and blessings be upon him and his family) said: "O Ali عليه السلام, do not approach your wife for intimacy at the beginning, middle, or end of the month, for insanity, leprosy, and mental disorder may affect her and your child. O Ali عليه السلام, do not engage in intimacy with your wife after noon, for if a child is conceived at that time, it may be cross-eyed, and Satan rejoices at cross-eyed humans. O Ali عليه السلام, do not speak during intimacy, for if a child is conceived, there is a risk that it may be born mute. And let no one look at the private parts of his wife; rather, he should lower his gaze during intimacy, for looking at the private parts causes blindness in the offspring. O Ali عليه السلام, do not engage in intimacy with your wife while imagining another woman, for I fear that if a child is conceived, it may be born as an effeminate or feminine-minded person. O Ali عليه السلام, if a person is in a state of major ritual impurity (junub) while in bed with his wife, he should not recite the Quran, for I fear that a fire from the sky may descend upon them and burn them." The compiler of this book, may Allah سبحانه وتعالى have mercy on him, explained that the prohibition refers specifically to the recitation of the verses of prostration (Ayat al-Aza'im), and not to other parts of the Quran. The Messenger of Allah سبحانه وتعالى (peace and blessings be upon him and his family) continued saying: "O Ali عليه السلام, do not engage in intimacy with your wife unless you have a cloth with you and she has a cloth with her, and do not wipe yourselves with the same cloth, for the desire will accumulate upon desire, which leads to enmity between you, eventually resulting in separation and divorce. O Ali عليه السلام, do not have relations with your wife while standing, for that is the behavior of donkeys. If a child is conceived in that state, he will urinate in the bed like donkeys that urinate everywhere. O Ali عليه السلام, do not have relations with your wife on the night of Eid al-Adha, for if a child is conceived, he may be born with six fingers or four fingers. O Ali عليه السلام, do not engage in intimacy with your wife under a fruit-bearing tree, for if a child is conceived in such a place, he may become a harsh and ruthless killer or a commander over others." O Ali عليه السلام, do not have relations with your wife in the presence of the sun and its brightness unless you lower a covering to conceal yourselves, for if a child is conceived in such a state, he will live in misery and poverty until he dies. O Ali عليه السلام, do not engage in intimacy with your wife between the call to prayer (adhan) and the commencement of prayer (iqamah), for if a child is conceived, he will be eager to shed blood. O Ali عليه السلام, when your wife is pregnant, do not have relations with her unless you are in a state of ablution (wudu), for if a child is conceived, he will be blind of heart and stingy in hand. O Ali عليه السلام, do not have relations with your wife on the night of the middle of Shaban, for if a child is conceived, he will be unfortunate and may have a mark on his face. O Ali عليه السلام, do not have relations with your wife in the final days of the month, when only two days remain, for if a child is conceived, he will become a tax collector or an aide to oppressors, and the destruction of many people will be at his hands. O Ali عليه السلام, do not have relations with your wife on the rooftops of buildings, for if a child is conceived, he will become a hypocrite, a show-off, and an innovator in religion. O Ali عليه السلام, when you set out on a journey, do not engage in intimacy with your wife on the night of your departure, for if a child is conceived, he will spend his wealth inappropriately. The Messenger of Allah سبحانه وتعالى (peace and blessings be upon him and his family) then recited: "Indeed, the spendthrifts are brothers of the devils." O Ali عليه السلام, do not have relations with your wife when you are leaving on a journey of three days and nights, for if a child is conceived, he will become a supporter of every oppressor against you. O Ali عليه السلام, engage in intimacy with your wife on Monday nights, for if a child is conceived, he will be a guardian of the Book of Allah سبحانه وتعالى and content with what Allah سبحانه وتعالى, the Mighty and Majestic, has decreed. O Ali عليه السلام, if you have relations with your wife on Tuesday night and a child is conceived, he will be granted martyrdom after bearing witness to La ilaha illa Allah سبحانه وتعالى (There is no god but Allah سبحانه وتعالى) and that Muhammad is the Messenger of Allah سبحانه وتعالى. He will not be punished alongside the polytheists, and he will have a pleasant scent, a merciful heart, generous hands, and a tongue pure from gossip, lies, and false accusations. O Ali عليه السلام, if you have relations with your wife on Thursday night and a child is conceived, he will become a judge among judges or a scholar among scholars. If you have relations with her on Thursday during the time when the sun is at its zenith, and a child is conceived, Satan will not approach him until he reaches old age. He will be righteous and Allah سبحانه وتعالى, the Mighty and Majestic, will grant him safety in both religion and worldly matters. O Ali عليه السلام, if you have relations with her on Friday night and a child is conceived, he will become an eloquent speaker and a persuasive orator. If you have relations with her on Friday after the afternoon (Asr) prayer and a child is conceived, he will be known, famous, and a scholar. If you have relations with her on Friday night after the late evening (Isha) prayer, it is hoped that the child will be among the abdal (pious individuals), if Allah سبحانه وتعالى, the Exalted, wills. O Ali عليه السلام, do not have relations with your wife in the early hours of the night, for if a child is conceived, there is a risk that he may become a sorcerer and one who prefers the worldly life over the Hereafter. O Ali عليه السلام, safeguard this advice of mine just as I have preserved it from Jibril عليه السلام."
