وَمِنهُمُ الَّذينَ يُؤذونَ النَّبِيَّ وَيَقولونَ هُوَ أُذُنٌ ۚ قُل أُذُنُ خَيرٍ لَكُم يُؤمِنُ بِاللَّهِ وَيُؤمِنُ لِلمُؤمِنينَ وَرَحمَةٌ لِلَّذينَ آمَنوا مِنكُم ۚ وَالَّذينَ يُؤذونَ رَسولَ اللَّهِ لَهُم عَذابٌ أَليمٌ

And among them are those who abuse the Prophet and say, "He is an ear." Say, "[It is] an ear of goodness for you that believes in Allah and believes the believers and [is] a mercy to those who believe among you." And those who abuse the Messenger of Allah - for them is a painful punishment.
