Sayyiduna Anas (may Allah be pleased with him) states that the angels said four takbirs over the funeral of Adam (peace be upon him); Sayyiduna Abu Bakr (may Allah be pleased with him) said four takbirs over the funeral of the Prophet (peace and blessings be upon him); Sayyiduna Umar (may Allah be pleased with him) said four takbirs over the funeral of Abu Bakr (may Allah be pleased with him); Sayyiduna Suhayb (may Allah be pleased with him) said four takbirs over the funeral of Umar (may Allah be pleased with him); Sayyiduna al-Hasan bin Ali (may Allah be pleased with them both) said four takbirs over the funeral of Ali (may Allah be pleased with him); and Sayyiduna al-Husayn (may Allah be pleased with him) said four takbirs over the funeral of al-Hasan (may Allah be pleased with him). The chain of this hadith is sahih (authentic), but the two Shaykhs did not record it. Mubarak bin Fadalah is of such a rank in asceticism and knowledge that a narrator like him is not criticised; however, the two Shaykhs did not take his narrations because of the weakness of his memory. There is a supporting hadith (shahid) for this hadith, as follows:

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) states that the takbirs which the Messenger of Allah (peace and blessings be upon him) said over a funeral the last time were four; Sayyiduna Umar (may Allah be pleased with him) said four takbirs over Abu Bakr (may Allah be pleased with him); Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said four takbirs over Umar (may Allah be pleased with him); Sayyiduna al-Hasan bin Ali (may Allah be pleased with them both) said four takbirs over Ali (may Allah be pleased with him); Sayyiduna al-Husayn bin Ali (may Allah be pleased with them both) said four takbirs over al-Hasan (may Allah be pleased with him); and the angels said four takbirs over Adam (peace be upon him). It is not hidden from me that al-Furat bin al-Sa'ib does not meet the condition of this book; I have presented it only as a supporting narration (shahid).
