1. My father narrated to me, he said: Sa'd b. Abdullah narrated to us, he said: Ahmad b. Muhammad narrated to us, from al-Husayn b. Sa'eed, from Ibn Abi 'Umayr, he said: Ahmad b. al-Nadr al-Khazzaz narrated to me, from 'Amr b. Shimr, from Jabir, from Abu Ja'far عليه السلام, he said: "O Jabir! Whoever enters the month of Ramadan and fasts its days, stands in prayer during its nights, guards his chastity, guards his tongue, lowers his gaze, and refrains from harming others, he will emerge free of sins as the day his mother bore him." I said: "May I be your ransom! How excellent is this hadith!" He said: "How stringent is its condition."
