Qard Hasan (a beautiful/goodly loan) is mentioned many times by Allah in the Qur’an
to show the beauty and rewards of giving
ان المصدقين والمصدقات واقرضوا الله قرضا حسنا يضاعف لهم ولهم اجر كريم
Indeed, the men who practice charity and the women who practice charity and [they who] have loaned Allah a goodly loan – it will be multiplied for them, and they will have a noble reward.
Surah Al-Hadid 57:18
مَن ذَا الَّذي يُقرِضُ اللَّهَ قَرضًا حَسَنًا فَيُضاعِفَهُ لَهُ وَلَهُ أَجرٌ كَريمٌ
Who is it that will lend Allah a goodly loan,that He may multiply it for him and [that] there may be a noble reward for him?
Surah Al-Hadid 57:11
إِن تُقرِضُوا اللَّهَ قَرضًا حَسَنًا يُضاعِفهُ لَكُم وَيَغفِر لَكُم ۚ وَاللَّهُ شَكورٌ حَليمٌ
If you lend Allah a good loan, He shall multiply it for you and forgive you,and Allah is All-Appreciative, All-Forbearing.
Surah Al-Taghabun 64:17
