"Whoever fasts it and prays during its nights with faith and seeking reward (iḥtisāban)."(1)

2210 – Muḥammad ibn ʿAbd Allāh ibn al-Mubārak informed us, saying: Abū Hishām narrated to us, saying: al-Qāsim ibn al-Faḍl narrated to us, saying: al-Naḍr ibn Shaybān narrated to us, saying: I said to Abū Salamah ʿAbd al-Raḥmān: "Narrate to me something you heard from your father, which your father heard from the Messenger of Allah, may Allah bless him and grant him peace, with no one between your father and the Messenger of Allah, may Allah bless him and grant him peace, concerning the month of Ramadan."

(1) Its chain of transmission is weak, like the preceding one. It is found in "al-Sunan al-Kubrā" under number (2530).

See also what precedes and follows it.
(2) The word "fasting" (ṣiyām) is not in (M).
(3) In one copy of (H), there is an addition after it: "upon you."
(4) Its chain of transmission is weak, like the two preceding ones. Abū Hishām is al-Mughīrah ibn Salamah al-Makhzūmī. It is found in "al-Sunan al-Kubrā" under number (2531).
It has been mentioned in the two preceding entries.
Al-Sindī said: His saying "I have established" (sananatu) is in the first-person form, meaning: I have recommended it for you. He said "for you" because it is pure benefit with no harm at all—whoever does it attains a great reward, and whoever abandons it bears no sin.
(5) The phrase "ibn Abī Ṭālib" is from (H).
(6) The phrase "ibn ʿAmr" is from (M), and he is al-Raqqī.
