Abu Bakr (رضي الله عنه) on Prophet’s (صلى الله عليه وسلم) passing away
Al-Bukhari recorded that `A’ishah (رضي الله عنها) said that Abu Bakr (رضي الله عنه) came riding his horse from his dwelling in As-Sunh. He dismounted, entered the Masjid and did not speak to anyone until he came to her ﴿in her room﴾ and went directly to the Prophet (صلى الله عليه وسلم), who was covered with a marked blanket. Abu Bakr (رضي الله عنه) uncovered his face, knelt down and kissed him, then started weeping and proclaimed, “My father and my mother be sacrificed for you! Allah will not combine two deaths on you. You have died the death, which was written for you.”
Ibn `Abbas (رضي الله عنه) narrated that Abu Bakr (رضي الله عنه) then came out, while `Umar (رضي الله عنه) was addressing the people, and Abu Bakr (رضي الله عنه) told him to sit down but `Umar (رضي الله عنه) refused, and the people attended to Abu Bakr (رضي الله عنه) and left `Umar (رضي الله عنه).
Abu Bakr (رضي الله عنه) said, “To proceed; whoever among you worshipped Muhammad (صلى الله عليه وسلم), then Muhammad (صلى الله عليه وسلم) is dead, but whoever worshipped Allah, Allah is alive and will never die. Allah said,
﴿وَمَا مُحَمَّدٌ إِلاَّ رَسُولٌ قَدْ خَلَتْ مِن قَبْلِهِ الرُّسُلُ أَفإِيْن مَّاتَ أَوْ قُتِلَ انقَلَبْتُمْ عَلَى أَعْقَـبِكُمْ وَمَن يَنقَلِبْ عَلَى عَقِبَيْهِ فَلَن يَضُرَّ اللَّهَ شَيْئاً وَسَيَجْزِى اللَّهُ الشَّـكِرِينَ ﴾
(Muhammad (صلى الله عليه وسلم) is no more than a Messenger (صلى الله عليه وسلم) and indeed (many) Messengers have passed away before him. If he dies or is killed, will you then turn back on your heels And he who turns back on his heels, not the least harm will he do to Allah; and Allah will reward the grateful.)”
The narrator added, “By Allah, it was as if the people never knew that Allah had revealed this verse before until Abu Bakr recited it, and then whoever heard it, started reciting it.” Sa`id bin Al-Musayyib said that `Umar (رضي الله عنه) said, “By Allah! When I heard Abu Bakr (رضي الله عنه) recite this Ayah, my feet could not hold me, and I fell to the ground.”
