From him, from Ali ibn Sulayman, who said: Ali ibn Abi Khulays narrated to us, who said: Ahmad ibn Muhammad ibn Mutahhar narrated to me: I wrote to Abu Muhammad (Imam al-Askari عليه السلام), peace be upon him: “A man has narrated from your forefathers, peace be upon them, that the Messenger of Allah سبحانه وتعالى, may Allah سبحانه وتعالى bless him and his family, did not increase in prayer during the Month of Ramadan beyond what He صلى الله عليه وعلى آله وسلم used to pray on other days.” Imam عليه السلام, peace be upon him, responded in his own handwriting: “He has lied, may Allah سبحانه وتعالى tear his mouth! Pray every night in the Month of Ramadan twenty rak’ahs until the twentieth of the month. And pray on the night of the twenty-first; one hundred rak’ahs, and pray on the night of the twenty-third; one hundred rak’ahs, and pray every night of the last ten nights; thirty rak’ahs.”
