Abu Hurairah narrated that the Messenger of Allah (ﷺ) said:“May the man before whom I am mentioned - and he does not send Salat upon me - be humiliated. And may a man upon whom Ramadan enters and then passes, before he is forgiven, be humiliated. And may a man whose parents reached old age in his presence, and they were not a cause for his entrance to Paradise, be humiliated.”
