وَقَالَ (عليه السلام):
Amir al-mu'minin, peace be upon him, said:
لاَ يُزَهِّدَنَّكَ فِي الْمَعْرُوفِ مَنْ لاَ يَشْكُرُهُ لَكَ،
If someone is not grateful to you, that should not prevent you from good actions,
فَقَدْ يَشْكُرُكَ عَلَيْهِ مَنْ لاَ يَسْتَمْتِعُ بِشَيْءٍ مِنْهُ،
because (possibly) such a person will feel grateful about it who has not even drawn any benefit from it,
وَقَدْ تُدْرِكُ مِنْ شُكْرِ الشَّاكِرِ أَكْثَرَ مِمَّا أَضَاعَ الْكَافِرُ
and his gratefulness will be more than the ingratitude of the denier;
(وَ اللَّهُ يُحِبُّ الْمُحْسِنِينَ) .
And Allah loves those who do good. (Qur'an, 3:134,148; 5:93)
