It is narrated from Hazrat Haritha (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: One of you acquires livestock and continues to participate in congregational prayer for some time. Then, due to the increase in his livestock, he faces difficulties and thinks that he should find a place for his animals with more grass than this. So, he moves from there and starts participating only in the Friday prayer. After some time, he faces difficulties again and, according to his previous thinking, moves from there as well, and neither attends the congregation nor the Friday prayer. Thus, a seal is set upon his heart.
