Imam Ali ibn Abi Talib said: “The words ‘Laa Ilaaha Illallaah’ move upwards, as soon as they come out from the mouth of a Muslim, and clearing away all sins that they make contact with, settle down with the good deeds.” Imam Muhammad Baqir said; "Nothing brings more rewards than the regular recitation of ‘Laa Ilaaha Illaallaah’".
Imam Jafar Sadiq said: "The good deeds of a person who recite one hundred times the words ‘Laa Ilaaha Illaallaah’ carry more weight than all other good actions, done on that day, except, of course, of that person who has recited the same a greater number of times."

(4) Al Aakhiru (The Last) {801} الأخر Whatever work taken in hand wins permanent success if Al Aakhiru is recited regularly. Love and respect of all wait in every walk of life.
