Could you please advice me how to react when some one praises you?
As long as you know yourself, this shouldn’t add any value to you nor it should hurt you if they don’t praise you. Imam Ahmed Ibn Hanbal said that the sign of true sincerity is not to be affected by praise or blame from people. Therefore, you should ask them kindly not to say these things as the Prophet salla Allahu alaihi wa sallam has denied people from praising others in their presence and said that this is like slaughtering them. You should also stive to be better than they think of you as Abu Bakr, may Allah be pleased used to say: Oh Lord make me better than they believe in me, forgive me what they don’t know and don’t hold me accountable to what they say about me.
