Abdullah ibn Abbas RA narrates that the Prophet Muhammad SAW said that whomsoever recites the above Du'a for 1000 times at anytime within the day, Allah Ta'ala has indeed protected him and saved him from His Punishment. And at the end of his life he will be called by the name: "Atiqullah" ("Made Noble by Allah").
It is common that when people sit together with family, friends and acquaintances - there is always tendency to indulge in backbiting, slandering, and evil statements; all of which are sinful.
Rasulullah SAW is reported to have said that – whomsoever recites the above Kalimah, Allah Ta’ala shall have written for him: two million rewards. In the month of Ramadhan, for every good deed – it is multiplied 70 folds. Hence – by just reciting it once – it shall be written for him 140 million rewards and for how much he/she will recite – the equivalent reward is what he/she will receive. (At-Targhib Wat-Tarhib)
The Prophet SAW's companion – Saiyidina Thauban RA narrates that The Prophet Muhammad SAW said that – whomsoever recites this Du’a in the morning and in the evening, hence it will become compulsary for Allah to be pleased with the reader of this Du’a on the Day of Qiyamah and (Allah) will place him/ her into Paradise.
It is narrated in the Book of Tabrani, the Prophet Muhammad SAW said:
“I guarantee that I will hold the hand of the reader (of this Du’a) and place him in Paradise.”
(Abu Dawud, Tirmidhi, Nasa’i and Ibn Majah)
