Q 5: There are some religious figures
who beat tambourines and drums and build Masjids (mosques) on graves.
They sacrifice sheep, cows, camels, etc. For these graves and collect money from people monthly and yearly. Are they included in those meant by the Ayah (Qur'anic verse) that declares:
"Those whose efforts have been wasted in this life while they thought that they were acquiring good by their deeds.
Yes, they are included in the people meant by the Ayah, for their sacrificing for the sake of anyone other than Allah is an act of Shirk (associating others with Allah in His Divinity or worship). As for their beating tambourines and drums, it is a sinful and Munkar (that which is unacceptable or disapproved of by Islamic law and Muslims of sound intellect) act. May Allah guide them and bless them with repentance to Him (Glorified be He) (Part No. 1; Page No. 203) from Shirk (associating others with Allah in His Divinity or worship) and other sins.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
