Sayyiduna Abu Hurairah (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said: "On the Day of Resurrection, the Prophets will be gathered on riding animals so that they may come from their graves to the plain of gathering. Salih (peace be upon him) will be mounted on a she-camel, my sons Hasan and Husayn (may Allah be pleased with them both) will ride on my she-camel ‘Adba’, and I will be raised on Buraq, whose one stride will reach as far as its sight extends. Bilal will be on one of the camels of Paradise; he will call the Adhan purely and will truthfully proclaim the words of testimony. When he says «أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللّٰهِ» , all the believers, former and latter, will bear witness for him, so for whom it is accepted, it will be accepted, and from whom it is rejected, it will be rejected."
