What is your opinion on the supplication "O Allah, heal the Muslims" with the feeling that it may not be realized in this world, and can it be a provision for them in the Hereafter or benefit some of them? And what are the desirable and beneficial supplications for the Ummah?

A Muslim should be concerned with the affairs of their fellow Muslims and supplicate for them for forgiveness, healing, or any matter that would lead to the betterment of their conditions. Ibn Abbas related that prayers should be invoked upon the Prophet, peace and blessings be upon him, and supplications for forgiveness should be made for Muslim men and women. The supplication of a Muslim for their Muslim brother in their absence is answered, and the angels say 'Ameen' to it. So, do not abandon supplicating for Muslims, for there is reward in it, and even if the answer is not realized, it is a stored reward for you or averts evil from you. Comprehensive and beneficial supplications for the Ummah can be used, such as: "O Allah, relieve the distress of the Muslims, grant them steadfastness upon Your law, and grant them victory over their enemies."
