Abu Bakr al-Siddiq (may Allah be pleased with him) was the most deserving of the Muslims to be the successor (caliph) of the Messenger of Allah (blessings and peace of Allah be upon him) after his death, regardless of the objections of the objectors and the extreme innovators. There is a great deal of evidence and proof from the Prophet (blessings and peace of Allah be upon him) concerning this matter, including this hadith. When the Prophet (blessings and peace of Allah be upon him) fell sick, he instructed Abu Bakr (may Allah be pleased with him) to succeed him in leaving the Muslims in prayer. This was an indication from the Prophet (blessings and peace of Allah be upon him) as to who was most deserving of succeeding him and most deserving and capable of continuing his mission. When the Prophet (blessings and peace of Allah be upon him) felt a little better and felt able to come out to the prayer, he came out, at a time when Abu Bakr (may Allah be pleased with him) was leading the people in prayer. When Abu Bakr (may Allah be pleased with him) saw him, he wanted to move back for the Prophet (blessings and peace of Allah be upon him), but the Prophet (blessings and peace of Allah be upon him) gestured to him, telling him to stay where he was. Then he sat in line with him, not ahead of him and not behind him. So the Messenger of Allah (blessings and peace of Allah be upon him) was the imam, and Abu Bakr (may Allah be pleased with him) was following the prayer of the Prophet (blessings and peace of Allah be upon him); he was standing and the Prophet (blessings and peace of Allah be upon him) was sitting, and the people were also standing, following the prayer of Abu Bakr (may Allah be pleased with him), because they could not see the Prophet (blessings and peace of Allah be upon him) or hear his voice, as he was so weak. Thus they were following Abu Bakr (may Allah be pleased with him), who was following the Prophet (blessings and peace of Allah be upon him) in his prayer. And it was said that in fact the Prophet (blessings and peace of Allah be upon him) was an imam for Abu Bakr, and Abu Bakr was an imam for the people standing behind him, so that prayer had two imams. Based on that, the Messenger of Allah (blessings and peace of Allah be upon him) prayed as an imam whilst sitting, when the people behind him were standing. There is a command to follow the imam, so if he prays standing, the one praying behind him should also pray standing, and if he prays sitting, then the one who is praying behind him should also pray sitting, as it says in the hadith narrated by al-Bukhari: “If he prays sitting, then pray sitting, all of you.” The response to this is that Abu Bakr had started to lead them in prayer standing, and he did not start out sitting. So if the imam needs to sit down during his prayer, when he started the prayer standing, the one who is praying behind him should complete his prayer standing. Thus we may reconcile the two hadiths. And it was said that the command to sit behind an imam who is sitting was abrogated by the Prophet’s last action, as narrated in this hadith, because it was the last thing that he did, shortly before he (blessings and peace of Allah be upon him) died. This hadith provides evidence that Abu Bakr (may Allah be pleased with him) was the best of the people after the Prophet (blessings and peace of Allah be upon him) and the most deserving of being his successor (caliph). It indicates that it is permissible to pray sitting, for one who does not have the strength to stand. It highlights the proper etiquette with one who is older or of higher status, as Abu Bakr wanted to move back because of the status of the Messenger of Allah (blessings and peace of Allah be upon him). It indicates that it is permissible for the imam to stop leading the prayer and start following someone else, without interrupting his prayer. It also encourages the Muslim to regularly attend the prayers in congregation..
