The Virtue - & Protection - awarded to the one who says Laa ilaaha illallaah, wahdahu laa shareeka lahu....
Aboo Hurayrah رضى الله عنه narrated that the Messenger of Allaah صلى الله عليه وسلم said: ”Whoever said:
« لاَ إِلَهَ إِلَّا اللَّهُ، وَحْدَهُ لاَ شَرِيكَ لَهُ، لَهُ المُلْكُ وَلَهُ الحَمْدُ، وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ »
((There is nothing that deserves to be worshipped in truth except Allaah, He is Alone and has no partner, to Him belongs the dominion and to Him belongs all praise, and He is All-Powerful over all things)) After he prays the morning prayer (al-ghadaah) ten times, Allaah عزوجل writes for him 10 hasanaat and removes from him 10 sayyiaat, and raises him 10 darajaat, and he gets the equivalent of freeing 2 slaves from the offspring of Ismaa’eel, and if he says it when he reaches evening, he gets the like of thatو and for him is a hijaab (barrier) from shaytaan until he reaches morning.” [1]
And in another wording, he - صلى الله عليه وسلم - said:
”Whoever said:
« لاَ إِلَهَ إِلَّا اللَّهُ، وَحْدَهُ لاَ شَرِيكَ لَهُ، لَهُ المُلْكُ وَلَهُ الحَمْدُ، وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ »
((There is nothing that deserves to be worshipped in truth except Allaah, He is Alone and has no partner, to Him belongs the dominion and to Him belongs all praise, and He is All-Powerful over all things)) 100 times in a day, he will get a reward equal to freeing ten slaves, and one-hundred good deeds will be written for him, and one-hundred bad deeds will be removed from him, and he will be protected from shaytaan on that day until he reaches the evening, and nobody will come with something superior to what he came with, except one who has done more than that."
