It wasnarrated that 'Abdullah bin 'Amr said:
"The Messenger of Allah(ﷺ) said: 'There are two characteristics which no Muslim manacquires but he will enter Paradise. They are easy but those who dothem are few. At the end of every prayer he should glorify Allah (bysaying Subhan Allah) ten times, extol Him (by saying Allahu Akbar)tentimes, and praise Him (by saying Al-Hamdu Lillah) ten times.' Isawthe Messenger of Allah (ﷺ) counting them on his hand. 'Thatis onehundred and fifty (after all the prayers of the day) on thetongue,and one thousand and five hundred on the Scale. And when hegoes tohis bed, let him glorify Allah and praise Him and extol Himonehundred times. That will be one hundred on the tongue and onethousandon the Scale. Who among you does two thousand and fivehundred evilactions in one day?' They said: 'Who would not bekeen to do that?' Hesaid: 'But the Shaitan comes to anyone ofyou while he is performingprayer and says: 'Remember such andsuch, remember such and such,"until the person becomes distractedand does not understand (what heis saying). And he comes to him whenhe is in his bed, and makes himsleepy such that he sleeps.'"
