جامع الترمذي#3862Da'ifNarrated 'Abdullah bin Mughaffal:that the Messenger of Allah (ﷺ) said: "(Fear) Allah! (Fear) Allah regarding my Companions! Do not make them objects of insults after me. Whoever loves them, it is out of love of me that he loves them. And whoever hates them, it is out of hatred for me that he hates them. And whoever harms them, he has harmed me, and whoever harms me, he has offended Allah, and whoever offends Allah, [then] he shall soon be punished
