It was narrated that Anas bin Malik said: "Umm Sulaim came to the Prophet (ﷺ) and said: 'O Messenger of Allah (ﷺ), teach me some words that I may supplicate with during my prayer.' He said: 'Glorify Allah (by saying SubhanAllah) ten times, and praise Him (by saying Alhamdulilah) ten times, and magnify Him (by saying Allahu Akbar) ten times, then ask Him for what you need; He will say: 'Yes, yes.'
