The like of the previous narration is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) from the Messenger of Allah (peace and blessings be upon him). This hadith is sahih (authentic) on the condition of Muslim, but the two Shaykhs did not record it. My view is that Imam Muslim left it out because Abu Ishaq al-Fazari narrated it from al-A'mash as mawquf (stopping at the Companion).

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he said: "Any people who sit in a gathering and then disperse from it without remembering Allah and without sending blessings upon their Prophet (peace and blessings be upon him), that gathering will be a source of regret for them on the Day of Resurrection." This narration does not create any hidden defect ('illah) or weakness in the hadith of Suhayl, because the addition (concerning sending blessings) made by Sulayman bin Bilal and Ibn Abi Hazim is accepted, and Sa'id al-Maqburi has also narrated it with a connected chain (musnad) from Sayyiduna Abu Hurayrah (may Allah be pleased with him).

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Any people who gather and then disperse without remembering Allah, it is as though they have got up (and dispersed) from the carcass of a dead donkey."

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Supplication is the weapon of the believer, the pillar of the religion, and the light of the heavens and the earth." This hadith is sahih (authentic), because its narrator Muhammad bin al-Hasan al-Tall is regarded as truthful (saduq) among the Kufans.

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Caution is of no avail against destiny, while supplication benefits against what has already come down (of afflictions) and what has not yet come down. And indeed, when an affliction comes down, supplication meets it, and the two wrestle with each other until the Day of Resurrection." This hadith is sahih al-isnad (its chain is authentic), but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Thawban (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Nothing averts destiny except supplication, and nothing increases one's lifespan except righteousness (and good treatment of relatives), and indeed a person is deprived of provision because of a sin that he commits." This hadith is sahih al-isnad (its chain is authentic), but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Supplication benefits against what has already come down (of afflictions) and what has not yet come down, so, O servants of Allah, hold fast to supplication."

It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "There is no Muslim who makes a supplication in which there is no mention of sin or of severing the ties of kinship, except that Allah Almighty grants him one of three things: either his supplication is answered (in this world), or an evil equal to it is turned away from him, or an equal reward is stored up for him (in the Hereafter)." The Companions said: Then we will supplicate abundantly. He (peace and blessings be upon him) said: "Allah is more abundant (in giving) than that." This hadith is sahih al-isnad (its chain is authentic); however, the two Shaykhs did not record it through Ali bin Ali al-Rifa'i.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Supplicate to Allah while you are fully certain of its acceptance, and know that Allah Almighty does not accept the supplication of a heedless heart occupied with amusement." The chain of this hadith is sound; only Salih al-Murri narrated it, and he is one of the ascetics of Basrah, and the two Shaykhs did not record it.

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Do not be helpless (and lazy) in supplicating, for no one perishes while he has supplication." This hadith is sahih al-isnad (its chain is authentic), but the two Shaykhs (Bukhari and Muslim) did not record it.
