Hypocrites annoy the Prophet
Allah says,
ومنهم الذين يوذون النبي ويقولون
And among them are men who annoy the Prophet and say:
Allah says, some hypocrites bother the Messenger of Allah by questioning his character, saying,
هو أذن
he is (lending his) ear,
to those who say anything about us; he believes whoever talks to him. Therefore, if we went to him and swore, he would believe us.
Similar was reported from Ibn Abbas, Mujahid and Qatadah.
Allah said,
قل أذن خير لكم
Say: "He listens to what is best for you,''
he knows who's saying the truth and who is lying,
يومن بالله ويومن للمومنين
he believes in Allah; has faith in the believers,
he believes the believers,
ورحمة للذين آمنوا منكم
and is a mercy to those of you who believe,''
and a proof against the disbelievers,
والذين يوذون رسول الله لهم عذاب أليم
But those who annoy Allah's Messenger, will have a painful torment
