Sayyidina Abdullah ibn Amr (RA) reported that Allah’s Messenger said, ‘Two characteristics are such that if a Muslim man adopts them, he will be admitted to paradise. And, indeed, both of them are easy but those who put them in practice are few. Glorify Allah at the end of every salah ten times, praise, Him ten times and extol Him ten times. The narrator said I observed Allah’s Messenger (SAW) count them on his fingers. He said, “They are a hundred and fifty by the tongue, but one thousand and five hundred in the scale. And, when you take to your bed glorify Him, extol Him and praise Him a hundred times. That is a hundred on the tongue but a thousand in the scale. So which of you commits during the day and night two thousand and five hundred sins?’0 They (the sahabah . ) said, “Why can we not do it regularly?” He said, “The devil comes to one of you while he is engaged in his, salah and says, Remember this, Remember that, till he finishes his salah and perhaps does not do it. And when he goes to bed, the devil comes to him and does not cease tc, induce sleep over him till he is asleep.”
