السلام عليكم ورحمة الله وبركاته
 أحسن الله إليكم شيخنا If one gets whispers from the Shaytan about fellow muslims, is it allowed to make dua for them to fight these thoughts and silence them? بارك الله فيكم

Ustadh AbdulAziz al-Haqqan

Yes, this is good, and du'a for your brother in his absence is answered, with the angel saying, and for you the same (Muslim). Also seek refuge in Allah from these thoughts and turn away from them.
