Questioner: Is it permissible to have an ikhwānī organization come to a masjid that claims Salafiyyah and have a sadaqah (charity) event such as giving out food to the poor in the masjid?
Shaykh Fawāz ibn 'Alī al-Madkhalī (حفظهالله): It is obligatory not to take anything from them. It is obligatory not to accept anything from these deviant groups because after they give you something they are going to come and rub it in your face. This is the way of the deviants. They give you sadaqah, then they will come and rub it in your face that they did you a favour, and this is one of the major sins. So what you should do is distance yourselves from them; do not accept any wealth or anything else from them. Allāh (Subhāna wa Ta'alā) will give you something better than that instead of them, as Allāh said:
"وَمَن يَتَّقِ ٱللَّهَ يَجۡعَل لَّهُ ۥ مَخۡرَجً۬ا وَيَرۡزُقۡهُ مِنۡ حَيۡثُ لَا يَحۡتَسِبُۚ"
"And whosoever fears Allāh and keeps his duty to Him, He will make a way for him to get out (from every difficulty). And He will provide him from (sources) he never could imagine." [ aṭ- Ṭalāq: 2-3]
