I used to greet the Messenger of Allah ﷺ with the salam while he was in prayer, and he would return my greeting. Then one day I greeted him and he did not return it, which weighed on me.When he finished praying, I said, "Messenger of Allah, when I used to greet you during prayer, you would return my greeting."He replied, "Allah brings about in His affair whatever He wills."
حدثنا محمد بن فضيل حدثنا مطرف عن أبي الجهم عن أبي الرضراض
كنت أسلم على رسول الله ﷺ في الصلاة فيرد علي فلما كان ذات يوم سلمت عليه فلم يرد علي فوجدت في نفسي فلما فرغ قلت يا رسول الله إني إذا كنت سلمت عليك في الصلاة رددت علي قال فقال إن الله عز وجل يحدث في أمره ما يشاء
Its isnad is sahih. Mutarrif is Ibn Tarif. Abu Jahm is Sulayman bin Jahm bin Abu Jahm Ansari Harithi Juzjani, and he was a trustworthy tabii, deemed reliable by Ajli, Ibn Hibban, and others.Abu Radrad was a tabii. Ibn Saad gave his biography (6/141), saying, "He narrated from Abdullah, from the Prophet ﷺ, concerning prayer." The Hafiz mentioned him in Tajil (130) under the name Radrad and said, "He is Abu Radrad, more to come under the kunyas," but then did not mention him under the kunyas, so perhaps he forgot.Bukhari gave his biography in Tarikh al-Kabir (2/1/311–313), saying, "Radrad heard Qays bin Thalaba, from Abdullah, 'I used to greet the Prophet ﷺ with salaam during prayer, and he would return the greeting. Then I greeted him and he did not return it, and he said, "Allah brings about of His affair whatever He wills."'"This was reported by Ahmad bin Saeed, from Ishaq Saluli, who heard Abu Kudayna, from Mutarrif, from Abu Jahm. Some said he was "from Banu Qays bin Thalaba."The eminent scholar Sheikh Abdul-Rahman bin Yahya Yamani, the editor of Tarikh al-Kabir printed in Hyderabad, examined this dispute with detailed and precise research, which one should consult and benefit from.The summary of his research is that Abu Kudayna alone, among those transmitting from Mutarrif, named him Radrad, and this is the narration that Bukhari relied on exclusively. As for the statement "heard from Qays bin Thalaba," this is an error, for there is no one among the tabiin named Qays bin Thalaba. Rather, it is a pre-Islamic name to which the tribe is traced, and the correct reading is "one of Banu Qays bin Thalaba." Perhaps the phrase "one of Banu" was miscopied by some narrators and read as "he narrated to me." Abu Radrad was mentioned by Ibn Hibban in Thiqat, and he quoted from Lisan Mizan (4/477), "Daraqutni said, 'Abu Kudayna erred in this. It is rather, from Abu Jahm, from Radrad, a man from Banu Qays bin Thalaba, from Ibn Masud.' This is the correct version. However, I prefer the narration of Musnad here, and in what will come at 3944, that he is Abu Radrad," said the eminent scholar Sheikh Abdul-Rahman Yamani.The two narrations can be reconciled by saying that he was Radrad, Abu Radrad, meaning his kunya matched his given name, which does occur elsewhere, and this is a plausible possibility. The hadith carries the same meaning as the one before it.
