• “To believe in Allah, His Angels, His Scriptures, His Messengers, Paradise, Hell-Fire, the scale of deeds, to believe in resurrection after death, and in destiny whether good or bad.”.

(1) He testifies that there is no God but Allah and that I am Allah’s Messenger and He sent me with the truth.
(2) He believes in death (being certain and does pious deeds before that). (3) He believes in resurrection after death, and
(4) He believes in predestination.” .
• “A strong believer is better to Allah than a weak one, and both are good. Adhere to that which is beneficial for you. Keep asking Allah for help and do not refrain from it.
