Re: When a pious person died they make a place of worship at his grave
The Companions (Allah is pleased with them) would look for ways to help the dead not ask them for help!!!
Another thing that may reach the deceased is sadaqah (charity) given on his behalf, because ‘Aa’ishah (may Allaah be pleased with her) reported that a man said to the Prophet (peace and blessings of Allaah be upon him): “My mother has passed away, and if she could have spoken, she would have given something in charity. Will she receive a reward if I give something on her behalf?” He said, “Yes.” (Reported by al-Bukhaari, Fath, 1388)
