(a) It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "The first time (of prayer) is the good pleasure of Allah, and the last time is the pardon of Allah." (b) A similar hadith is narrated from Ibn Umar (may Allah be pleased with them both). (c) Abu Ahmad (Ibn Adi) (may Allah have mercy on him) said: This is how Ibn Humayd used to narrate it to us, saying "Ubaydullah" in this chain, and the correct version is what Ibn Sa'id and Ibn Asbat narrated to us; yet this hadith with this chain is batil (false), whether "Abdullah" or "Ubaydullah" is named in it. (d) The Shaykh said: This hadith is known only through Ya'qub bin al-Walid al-Madani. Ya'qub is munkar al-hadith (his narrations are rejected); Yahya bin Ma'in (may Allah have mercy on him) declared him weak, and Imam Ahmad bin Hanbal (may Allah have mercy on him) and the rest of the hadith masters declared him a liar and attributed fabrication to him. We seek refuge in Allah from being forsaken. It has also been narrated through other chains, all of which are weak.
