Musannaf Ibn Abi Shayba 9:1251

Al-Hasan ibn Musa narrated to us, from Hammad ibn Salamah, from ‘Ata’ ibn al-Sa’ib, from the nephew of ‘Alqamah, that Ibn Mas’ud, when he would have intercourse with his wife and ejaculate, he would say: "O Allah, do not grant the Shaytan any share in what You have provided us."
