The Al-Kulayni said...
The Al-Kulayni said, ‘From his father, from the one who narrated to him, from Al-Husayn Bin Al-Mukhtar, ‘Abu Abdullah -asws having said: ‘Amir-al-Momineen -asws said in a speech of his -asws : Place the affairs of your brother upon the best (interpretation) until there comes to you (evidence) which overturns it, and do not act upon conjecture of a word which has come out from your brother except that you find for it in goodness’.
[13] عن عبد الله بن جندب، قال: كتب إلي أبو الحسن الرضا (عليه السلام) «ذكرت- رحمك الله- هؤلاء القوم الذين وصفت أنهم كانوا بالأمس لكم إخوانا، و الذي صاروا إليه من الخلاف لكم، و العداوة لكم و البراءة منكم، و الذي تأفكوا به من حياة أبي (صلوات الله عليه و رحمته)».
From Abdullah Bin Jundab who said, ‘Abu Al-Hassan Al-Reza -asws wrote to me: ‘ You mentioned, may Allah -azwj have Mercy on you – these people, those whom you described that they used to be your brothers yesterday, and those who come to be adversaries to you, and have the enmity for you all and the disavowing from you , and those who spread lies from the life-time of my ‑asws father -asws ’.
So the destruction came to them from the safety of their precautions, and that was due to what their hands had earned, and your Lord is not in the least unjust to the servants [41:47] .
