Musannaf Ibn Abi Shayba 27:122

Ibn Fudayl narrated to us, from ‘Ata’ ibn al-Sa’ib, from Yahya ibn Ja’dah, from a man who narrated to him, from Umm Malik al-Ansariyyah, who said: Umm Malik came with a skin of ghee to the Messenger of Allah, may Allah bless him and grant him peace. The Messenger of Allah, may Allah bless him and grant him peace, ordered Bilal, so he squeezed it, then he returned it to her. She returned, and behold, it was full. She came to the Prophet, may Allah bless him and grant him peace, and said: "Has something been revealed about me, O Messenger of Allah?" He said: "And what is that, O Umm Malik?" She said: "You returned my gift to me." He called Bilal and asked him about that. He said: "By the One who sent you with the truth, I squeezed it until I felt ashamed." The Messenger of Allah, may Allah bless him and grant him peace, said: "Enjoy it, O Umm Malik; this is a blessing for which Allah has hastened its reward." Then he taught her that after every prayer, one should say: "Subhan Allah" (Glory be to Allah) ten times, "Alhamdulillah" (Praise be to Allah) ten times, and "Allahu Akbar" (Allah is the Greatest) ten times.
