Abu Dharr (May Allah be pleased with him) said:
The Messenger of Allah ﷺ was asked: "Tell us about a person who does some good deed and people praise him, will this be considered as showing off?" He replied, "This is the glad tidings which a believer receives (in this life)."

[Muslim].

وعن أبي ذر رضي الله عنه قال: قيل لرسول الله ﷺ : أرأيت الرجل يعمل العمل من الخير، ويحمده الناس عليه؟ قال: " تلك عاجل بشرى المؤمن" ((رواه مسلم)).
