Abdullah bin Umar reported,

I was with the Prophet ﷺ when Harmala bin Zayd came and sat before the Messenger of Allah ﷺ.He said, "Messenger of Allah, faith is here," pointing with his hand to his tongue, "and hypocrisy is here," pointing with his hand to his chest, "and he scarcely remembers Allah."The Prophet ﷺ remained silent. Harmala repeated this to him, and the Prophet ﷺ still said nothing. Then the Prophet ﷺ took hold of the tip of Harmala's tongue and said, "O Allah, grant him a truthful tongue and a grateful heart, bless him with love for me and love for those who love me, and turn his affairs toward what is good."Harmala said, "Messenger of Allah, I have brothers who are hypocrites, and I was their leader. Shall I not point them out to you?"The Prophet ﷺ replied, "No. Whoever comes to us as you have come, we will seek forgiveness for him as we have sought forgiveness for you. As for whoever persists in his sin, Allah has more right to deal with him. Do not tear away the covering from anyone."

عن ابن عمر قال

كنت عند النبي ﷺ إذ جاءه حرملة بن زيد فجلس بين يدي رسول الله ﷺ: فقال يا رسول الله، الإيمان ههنا، وأشار بيده إلى لسانه، والنفاق ههنا، وأشار بيده إلى صدره، ولا يذكر الله إلا قليلا، فسكت عنه النبي ﷺ، فردد ذلك عليه وسكت حرملة، فأخذ النبي ﷺ بطرف لسان حرملة فقال: اللهم اجعل له لسانا صادقا، وقلبا شاكرا، وارزقه حبي وحب من يحبني، وصير أمره إلى الخير فقال حرملة: يا رسول الله، إن لي إخوانا منافقين، كنت فيهم رأسا، أفلا أدلك عليهم؟ فقال النبي ﷺ: لا من جاءنا كما جئتنا استغفرنا له كما استغفرنا لك، ومن أصر على ذنبه فالله أولى به، ولا تخرق على أحد سترا.
