Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: There are two qualities; whoever guards them, they will admit him to Paradise. They are easy, but those who act upon them are few. The people asked: O Messenger of Allah! What are those two? He (peace and blessings be upon him) said: After every obligatory prayer, say ten times: Alhamdulillah, Allahu Akbar, and SubhanAllah. Then, when you come to your bed, say one hundred times: SubhanAllah, Allahu Akbar, and Alhamdulillah. These will be two hundred and fifty words on the tongue, but on the scale, they will be two thousand five hundred. (Now tell me) who among you commits two thousand five hundred sins in a day and night? The companions said: Then why are those who act upon them few? He (peace and blessings be upon him) said: Satan comes to you during prayer and starts reminding you of your needs, so he (stands up immediately after the salam and) is unable to say these words. Similarly, he comes (at night) at the time of sleep and makes him sleep before he can say this remembrance, so he is unable to say these words. The narrator says: I saw that the Messenger of Allah (peace and blessings be upon him) used to count them with his hand.
