بسم الله الرحمن الرحيم

In case you have hurt your mother in any way, you should first ask her forgiveness and keep on supplicating. You need not give up and be hopeless. If a man supplicates wholeheartedly and does not commit an act that may be an obstacle in the acceptance of dua then his supplication is answered for sure. A believer who supplicates receives one of three things: Either he gets exactly what he asked for or some hardship or calamity is removed from him in return of his supplication or some certain reward is recorded for him in the Hereafter.
According to a narration: Allah shall call the slave on the Day of Judgement and say, “O My slave I ordered you to supplicate and promised to accept it”. Did you supplicate? He will say, “Yes.” Thereupon Allah will say none of your supplication was rejected. You supplicated that so and so pain should be removed and I answered it in the world. You supplicated to remove so and so pain but it was not removed, but I have recorded so and so reward for you in hereafter for the same. The holy Prophet Muhammad (may peace and blessings of Allah be upon him) said that each and every supplication shall be reminded him and he will also be reminded if it was answered in the world or its reward will be given in hereafter. On seeing the plentiful reward he would yearn would that none of his supplications would have been answered in the world so that he could get its reward in the hereafter.
Allah knows Best!
