Hadith no. 646 and 647 are repeats. Read here.
Anas bin Malik Al-Ansari, told me, “Abu Bakr used to lead the people in prayer during the fatal illness of the Prophet till it was Monday. When the people aligned (in rows) for the prayer the Prophet lifted the curtain of his house and started looking at us and was standing at that time. His face was (glittering) like a page of the Qur’an and he smiled cheerfully. We were about to be put to trial for the pleasure of seeing the Prophet, Abu Bakr retreated to join the row as he thought that the Prophet would lead the prayer. The Prophet beckoned us to complete the prayer and he let the curtain fall. On the same day he died.”
The Prophet did not come out for three days. The people stood for the prayer and Abu Bakr went ahead to lead the prayer. (In the meantime) the Prophet caught hold of the curtain and lifted it. When the face of the Prophet appeared we had never seen a scene more pleasing than the face of the Prophet as it appeared then. The Prophet beckoned to Abu Bakr to lead the people in the prayer and then let the curtain fall. We did not see him (again) till he died.
What lit the face of the Prophet (SAW) that day was seeing the Muslims praying together, all bowing down to the Almighty Allah. I wonder if he’d feel the same seeing the Muslims today: all of them not praying together, not bowing down to Allah. Sigh. May Allah bring back the days of glory.
