What is the ruling on lining up at the grave for condolences?

Question:
There is an innovation in the practice of offering condolences at the cemetery, where the deceased's relatives, such as his sons and brothers, line up on one side like a prayer row. Then the condolers approach them and greet them one by one. What is the ruling on this practice? Does it have a basis in the Shari'ah? And what is the proper way to offer condolences to the deceased's family at the cemetery?

Answer:
We are not aware of any basis for this, but the matter is easy. People offer condolences, whether at the cemetery, on the way before the burial, or after the burial in the mosque, on the way, or at home, in any place. The matter of condolences is broad.
As for lining them up in a row so that they are known and so that the condolers can seek them out, we are not aware of any basis for it, but the matter is light. This is because the goal is to make things easy for people so that they do not have to go around to their houses to offer condolences. If they find them at the cemetery nearby, they offer condolences and are spared a lot of effort. So, in my view, the matter is not severe; it is broad, if Allah wills.
Q: What is the innovation?
The Shaykh: I am not aware of anything specific in it, but if it is left, that would be good, if Allah wills. Otherwise, I do not know that it means: a known basis. Rather, this is a facilitation for condolences, and condolences are prescribed. They facilitate condolences for them in this way, and condolences are prescribed.
