What is God's Greatest Name, what is the reward for carrying the deceased's bier in a funeral procession, and will the supplication of one who prays before the Kaaba upon first seeing it, asking God to teach him His Greatest Name, be answered?

Scholars have differed regarding the Greatest Name of Allah, and the most preponderant opinion is that it is "Allah." Carrying the deceased, performing the funeral prayer over them, walking with them, and burying them holds immense reward. The Messenger of Allah (peace and blessings be upon him) said: "Whoever attends a funeral until he offers the prayer for it, will have one qirat of reward. And whoever attends it until it is buried, will have two qirats, each qirat is greater than Uhud." As for making a permissible supplication upon seeing the Kaaba for the first time, we hope it will be answered, because the supplication is made in the greatest place and at a time of humility, awe, and submission to Allah.
