Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: We asked the Prophet (peace and blessings be upon him) about the pace of walking with the funeral, and he (peace and blessings be upon him) said: "The pace is less than a trot. If it is good, it is hastened towards it; and if it is otherwise, then away with the people of the Fire. The funeral is followed, it does not follow; whoever goes ahead of it is not with it."
This hadith is da'if (weak); Yahya bin Abdullah al-Jabir is da'if (weak), and Abu Majid is majhul (unknown). What has preceded is sufficient.
It is mentioned from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that when he was on his deathbed, Ibn Umar and Ibn Abbas (may Allah be pleased with them both) came to him, and he said to them: "When you carry me, take me quickly, take me quickly."
