Remember Allah in good times and He will mention you in hard times

al-Hasan (al-Basree) said:

The wise man does not argue or seek to overcome with stratagem rather he propagates his wisdom. If it is accepted he praises Allaah and if it is rejected he praises Allaah

Reported by Abu Nu`aym ibn Hammaad in his Zawaa'id `alaz-Zuhd libnil Mubaarak (no. 30) and Ibn Battah in Ibaanatul-Kubraa (no. 611)

A man once asked Abû Al-Dardâ’ – Allah be pleased with him – for advice. He said:

Remember Allah in good times and He will mention you in hard times. When you remember those who have passed away, consider yourself like one of them. And when you think of involving yourself in some worldly matter, consider first what it will lead to in the end.

Siyar A’lâm Al-Nubalâ’

It is reported that Al-Awzaa'i said, 

“Follow the narrations [ways] of those who have preceded (the Salaf) even if people reject you; and beware of people’s opinions, even if they beautify them for you.”

Al-Aajurree, Kitaab Al-Shareerah Vol.1 p138; Ibn ‘Abd Al-Barr, Jaami’ Bayaan Al-‘Ilm wa Fadlihi Vol.3 p373.

Nasr ibn Mahmood al Balkhee said; Ahmad ibn Harb stated:

“I worshiped Allaah for fifty years, I wasn’t able to find the sweetness of worship until I forsook three things: 

1. I forsook seeking the acceptance of people, so I was able to speak the truth. 

2. I forsook the companionship of the sinner, so I was able to accompany the righteous. 

3. I forsook the sweetness of the life of this world, so I was able to find the sweetness of the afterlife.
