The Prophet (SAWA) said, ‘The most basic level of infidelity is for a man to hear a fellow brother say something and memorize it for future use against him in order to shame him with it. Those are worthless people indeed.
رسولُ اللهِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ) : أدنَى الكفرِ أنْ يَسمعَ الرّجُلُ مِن أخيهِ الكَلِمَةَ فيَحْفَظَها علَيهِ يُريدُ أنْ يَفْضَحَهُ بها ، اُولئكَ لا خَلاقَ لَهُم.
