Surah Luqman: 22
And whosoever submits his face to Allah, while he is a Muhsin, then he has grasped the most trustworthy hand-hold. And to Allah return all matters for decision.
Surah Luqman: 33
O mankind! Be afraid of your Lord, and fear a Day when no father can avail aught for his son, nor a son avail aught for his father. Verily, the Promise of Allah is true, let not then this present life deceive you, nor let the chief deceiver deceive you about Allah.
Surah Al Ahzab: 21
Indeed in the Messenger of Allah you have a good example to follow for him who hopes for Allah and the Last Day and remembers Allah much.
