The Messenger of Allah ﷺ said, "When you pray after Jumuah, pray four rakahs. If something hurries you, pray two rakahs in the mosque and two rakahs when you return."Ibn Idris said, "I do not know whether this hadith is from the Messenger of Allah ﷺ or not."
حدثنا ابن إدريس قال سمعت سهيل بن أبي صالح يذكر عن أبيه
قال رسول الله ﷺ إذا صليتم بعد الجمعة فصلوا أربعا فإن عجل بك شيء فصل ركعتين في المسجد وركعتين إذا رجعت قال ابن إدريس لا أدري هذا الحديث لرسول الله ﷺ أم لا
Its chain of transmission is sahih. Ibn Idris is Abdullah bin Idris Awdi, whose reliability was established earlier at 1379. We add here that Ibn Saad gave his biography in al-Tabaqat 6:271, saying, "He was trustworthy, reliable, a prolific transmitter of hadith, an authority, a man of sunnah and community." Ibn Abu Hatim also gave his biography at 2/2/8-9, as did Khatib in Tarikh Baghdad 9:415-421.This hadith will come again with this same chain at 9997. Muslim related it at 1:240, from Abu Bakr bin Abu Shayba and Amr Naqid, both from Abdullah bin Idris, with this chain, but he separated its ending, saying that Amr added in his version, Ibn Idris said, Suhayl said, "If something urgent comes up for you, pray two rakahs in the masjid, and two rakahs when you return." He also related it through other chains, in similar fashion, without this addition attributed to Suhayl.Abu Dawud related it at 1131 [1:439-440] from Ahmad bin Yunus, from Zuhayr bin Muawiya, and also from Muhammad bin Sabbah, from Ismail bin Zakariya, both of them from Suhayl, with the same chain. The wording of Ahmad bin Yunus matches the version given here, and at its end it reads, he (meaning Suhayl bin Abu Salih) said, "He said to me, meaning 'O my son, if you pray two rakahs in the masjid, then come to the dwelling or the house, pray two rakahs.'"This version, the version of Ahmad bin Yunus from Zuhayr, removes the doubt that Ibn Idris expressed here, and shows that this statement at the end of the hadith is not something the Prophet said, but rather is the speech of Abu Salih addressed to his son Suhayl. There is no contradiction between this version and Muslim's version from Amr Naqid from Abdullah bin Idris in treating it as the words of Suhayl. It may be that Ibn Idris sometimes doubted whether it was something the Prophet said, and at other times stated it was not something the Prophet said, attributing it instead to Suhayl. Whoever remembers correctly is an authority over whoever does not remember correctly.Bayhaqi likewise related it in Sunan al-Kubra 3:239-240, through the route of Ishaq bin Ibrahim and Hannad bin Sari, both of them from Abdullah bin Idris, and he mentioned the addition at the end from the version of Ishaq. He then said, Ahmad bin Salama (who transmitted from Ishaq) said, "The remaining statement in the hadith comes from the words of Suhayl."Ibn Majah related it at 1132 from Abu Bakr bin Abu Shayba and Abu Saaib, both of them from Ibn Idris, without the addition attributed to Suhayl or his father. Tirmidhi related it at 1:371 through the version of Sufyan bin Uyayna, from Suhayl, likewise without it, and said, "This is a hasan sahih hadith." Nasai likewise related it at 1:210 through the version of Jareer from Suhayl.As for his statement at the end, "Is this a saying of the Messenger of Allah ﷺ or not," this is how it appears in H, K, and M. In S it reads, "Is this a hadith of the Messenger of Allah or not," and this variant appears in the margin of M.
