Afraid?

Samarkand says that the person who does one good deed should be weary
of four things (imagine what a person who commits a sin should be
afraid of!) :
*. The fear of not being accepted because Allah says:
'Allah only accepts from those who fear.' [Maidah:27]
*. The fear of showing off, for Allah says:
'They have been instructed to worship Allah sincerely; religion isfor
him Alone.' [Bayinah: 5]
*. The fear of preserving the good deed because Allah says:
'Whoever brings a good deed shall have ten times its reward.' [An`am: 160]
*. The fear of being deserted in performing good deeds, for Allah says:
'And my guidance cannotcome except from Allah, in Him I trust and unto
Him I repent' [Hud: 88]
