Al-Irbād b. Sāriya said the Prophet used to recite al-Musabbihāt* before going to sleep, and say they contained a verse which is better than a thousand verses.
*These are said to be sūras 57, 59, 61, 62, 64, 87 which begin with the perfect, imperfect, or imperative of the verb sabbaha ('to glorify').
Tirmidhī and Abū Dāwūd transmitted it, and Dārimī transmitted it in mursal form on the authority of Khalid b. Ma'dān. Tirmidhī said this is a hasan gharīb tradition.
Abū Huraira reported God’s messenger as saying, “A sūra in the Qur’ān containing thirty verses interceded for a man till his sins were forgiven. It was ‘Blessed is He in whose hand is the kingdom.'” (Qur’ān, 67)
Ahmad, Tirmidhī, Abū Dāwūd, Nasā’i and Ibn Mājah transmitted it.
He reported God’s messenger as saying, “If someone recites Hā’ Mīm ad-Dukhān (Qur’ān, 44) any night, seventy thousand angels will ask forgiveness for him in the morning.”
Tirmidhī transmitted it, saying that this is a gharīb tradition and that ‘Umar b. Abū Khath'am the transmitter is declared to be weak. Muhammad, i.e. Bukhārī, said his traditions were rejected.
