At-Taubah - 9:61

وَمِنْهُمُ الَّذِينَ يُؤْذُونَ النَّبِيَّ وَيِقُولُونَ هُوَ أُذُنٌ قُلْ أُذُنُ خَيْرٍ لَّكُمْ يُؤْمِنُ بِاللّهِ وَيُؤْمِنُ لِلْمُؤْمِنِينَ وَرَحْمَةٌ لِّلَّذِينَ آمَنُواْ مِنكُمْ وَالَّذِينَ يُؤْذُونَ رَسُولَ اللّهِ لَهُمْ عَذَابٌ أَلِيمٌ
[9:61]
And there are some of them who molest the Prophet and say: He is one who believes every thing that he hears; say: A hearer of good for you (who) believes in Allah and believes the faithful and a mercy for those of you who believe; and (as for) those who molest the Messenger of Allah, they shall have a painful punishment.
Among them are men who molest the Prophet and say, "He is (all) ear." Say, "He listens to what is best for you: he believes in Allah, has faith in the Believers, and is a Mercy to those of you who believe." But those who molest the Messenger will have a grievous penalty.
And of them are those who vex the Prophet and say: He is only a hearer. Say: A hearer of good for you, who believeth in Allah and is true to the believers, and a mercy for such of you as believe. Those who vex the messenger of Allah, for them there is a painful doom.
