Al-Matalib al-'Aliyah 443 — Making up missed prayers

It is narrated from Silah bin Zufar (may Allah have mercy on him) that he said: "Sayyiduna Hudhayfah bin al-Yaman (may Allah be pleased with him) appointed me as his deputy. We prayed Zuhr, then we came to some people who were praying Zuhr, so we prayed with them as well. Then we prayed Asr, then we came to some people who were praying Asr, so we prayed with them as well. Then we prayed Maghrib, then we came to some people who were praying Maghrib, so we prayed with them as well (as a voluntary prayer). Then, when I was about to stand up for the third rak'ah in that second congregation of Maghrib, he held me back."
There is weakness in the chain of this report because of the presence of Layth bin Abi Sulaym, since he suffered from a decline of memory (ikhtilat) in his last years; however, the general concept of repeating the prayer to gain the virtue of congregation is established by other authentic hadith.
