Praise be to Allah.
We advise you to stick to good companions, and if you have to leave them because of some work, then fear Allaah and remember that He is always watching you, and He is greater than them. Allaah says (interpretation of the meaning):
“Surely, Allaah is Ever an All Watcher over you” [al-Nisaa’ 4:1]
“Who sees you (O Muhammad) when you stand up (alone at night for Tahajjud/late night prayers).
And your movements among those who fall prostrate (to Allaah in the five compulsory congregational prayers [al-Shu’araa’ 26:218-219]
“Be not sad (or afraid), surely, Allaah is with us”
Allaah is always watching you, so fear Allaah. Remember that you are in front of Him and that He can see you when you obey Him and when you disobey Him. So fear the punishment of Allaah and beware lest you do anything that earns His wrath. Allaah says (interpretation of the meaning):
“And Allaah warns you against Himself (His punishment)”
[Aal ‘Imraan 3:30]
“and fear none but Me” [al-Baqarah 2:40]
You have to be sincere towards Allaah and adhere firmly to the religion of Allaah when you are alone and when you are with your friends. Wherever you are, Allaah can hear what you are saying and can see what you are doing, so you have to feel more shy of Allaah than you do of your family and other people.
