Musannaf Ibn Abi Shaybah 31219 — What is said after the prayers

Taysalah said that Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: "Whoever says after every prayer and when he lies down on his bed: 'Allah is the Greatest, greatly so, by the count of the even and the odd, and of the perfect, pure and blessed words of Allah,' three times, and 'There is no one worthy of worship except Allah,' three times, these words will become a light for him in his grave, a light on the Bridge and a light on the Sirat, until they enter him into Paradise," or he said: "until he enters Paradise."
