Salim (may Allah have mercy on him) narrates that we set out for Makkah with Umm al-Mu'mineen Sayyidah Aisha (may Allah be pleased with her), and she used to set out with my father and also used to pray with him. Salim says that water for ablution was brought for Abdur Rahman bin Abi Bakr (may Allah be pleased with him), so Umm al-Mu'mineen Sayyidah Aisha (may Allah be pleased with her) said: O Abdur Rahman, complete the ablution thoroughly. I heard the Messenger of Allah (ﷺ) say: "Woe to the heels from the fire on the Day of Resurrection."
