As-Salaam alaikum, It has been related by Abu Mansur ad-Daylami in his Musnad called al-Firdaus, on the authority of Hudhayfa, may Allah be pleased with him, that the Messenger of Allah, Sallallahu alaihi Wasallam, said:-- "Seeking Forgiveness is the eraser of sins"... "ISTIGHFAR MAMHATU LILZUNUBI''. Imam Fudayl said: "When the servant says: 'ASTAGHFIRULLAH ( I seek forgiveness of Allah ) persistently, not only will his sins be wiped away, but it will have effect upon all those around him. Allah Ta'ala says:-- "Seek forgiveness of your Lord, verily He is Forgiving, He will send the heavens upon you abundantly and will reinforce you with wealth and sons and make for you Gardens and make for you rivers." In view of this, make ISTIGHFAR part of your daily Zikr...when you come to remember Allah in the mornings and evenings. Best Wishes.
