إِنَّ ٱللَّهَ لَا يَظْلِمُ مِثْقَالَ ذَرَّةٍۢ ۖ وَإِن تَكُ حَسَنَةًۭ يُضَٰعِفْهَا وَيُؤْتِ مِن لَّدُنْهُ أَجْرًا عَظِيمًۭا
Lo! Allah wrongeth not even of the weight of an ant; and if there is a good deed, He will double it and will give (the doer) from His presence an immense reward.
Surah An-Nisaa(4:40)
Sahih al-Bukhari
Belief
Chapter: Al-Jihad (fighting tn Allah's Cause) is a part of faith
Narrated Abu Huraira:
The Prophet (ﷺ) said, "The person who participates in (Holy battles) in Allah's cause and nothing compels him to do so except belief in Allah and His Apostles, will be recompensed by Allah either with a reward, or booty (if he survives) or will be admitted to Paradise (if he is killed in the battle as a martyr). Had I not found it difficult for my followers, then I would not remain behind any sariya going for Jihad and I would have loved to be martyred in Allah's cause and then made alive, and then martyred and then made alive, and then again martyred in His cause."
Sahih al-Bukhari 36
