Hadith 40-26

حَدَّثَنا الْحاكِم أَبُو عَلِي الحُسَيْنِ بْنِ أحْمَد الْبِيْهَقِيُّ قالَ حَدَّثَني مُحَمَّدِ بْنِ يَحْيَى الصُّوليُّ قالَ: حَدَّثَنا الغلابي قالَ: حَدَّثَنا أَحْمَدِ بْنِ عِيسَى بْنِ زِيْد أَنَّ الْمَأْمُونَ أَمَرَنِي بِقَتْلِ رَجُلٍ فَقَالَ اسْتَبْقِنِي فَإِنَّ لِي شُكْراً فَقَالَ وَمَنْ أَنْتَ وَمَا شُكْرُكَ فَقَالَ عَلِيُّ بْنُ مُوسَى‏ عَلَيْهِ السَّلامُ يَا أَمِيرَ الْمُؤْمِنِينَ أَنْشُدُكَ اللَّهَ أَنْ تَتَرَفَّعَ عَنْ شُكْرِ أَحَدٍ وَإِنْ قَلَّ فَإِنَّ اللَّهَ عَزَّ وَجَلَّ أَمَرَ عِبَادَهُ بِشُكْرِهِ فَشَكَرُوهُ فَعَفَا عَنْهُمْ.

Al-Hakim Abu Ali Al-Husayn ibn Ahmad al-Bayhaqi narrated that Muhammad ibn Yahya al-Sowli quoted on the authority of Al-Qalabi, on the authority of Ahmad ibn Isa ibn Zayd, “When Al-Ma’mun ordered a man to be killed, the man said, ‘Let me live since I have been grateful to you.’ He said, ‘Who are you to be grateful?’ Then Ali ibn Musa Ar-Ridha’ (a.s.) said, ‘O Commander of the Faithful! I adjure you by God the Highest that you appreciate what the people do - even if it is very little - since God the Highest ordered His servants to thank Him. They thanked Him and He forgave them.’”
