Is it permissible to reward a disbeliever if he does us good?
Machine translationRead the Arabic original
The questioner : It is permissible to do good to a disbeliever if he does us a favor, and if we do this?
The Shaykh : Whoever does you a good deed, reward him. This is the evidence for this hadith that is with us, which is proof of that. Therefore, I am assigning you the task of presenting to us tomorrow, if Allah wills, all the benefits derived from this hadith, on the condition that you do not consult *Fath al-Bari*.
The presenter : Good, another honor.
The Shaykh : And no other commentaries from you, right? So once you have finished what you have, you may consult it.
