The jurist of 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 is for 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 cannot come except from Allah, in Him I trust and unto Him I repent’ [Hud: 88]
