Will he who prays over a funeral and follows it to the graveyard receive two qirats if he leaves before its burial due to an emergency?

Following a Muslim funeral procession is a Sunnah (definition). Whoever prays over it and follows it until the burial is completed will receive two Qirats of reward, each Qirat like Mount Uhud. Whoever prays over it then departs before the burial will receive one Qirat. The fourth and most complete level is to remain after the burial is completed to seek forgiveness for the deceased and supplicate for their steadfastness; this is what earns the two Qirats. If the departure is due to necessity, then you will receive the full reward, Allah willing, as the Prophet, peace and blessings be upon him, said: "The excuse detained them."
