Musnad Ahmad Hadith 15539

It is narrated from Harith bin Ziyad that once, on the occasion of the Battle of the Trench, he presented himself in the service of the Prophet (ﷺ) while the Prophet (ﷺ) was taking the pledge of migration from the people. He said: O Messenger of Allah! Please include this person in the pledge as well. The Prophet (ﷺ) asked: Who is he? He replied: He is my cousin, Hut bin Yazid. The Prophet (ﷺ) said: I will not take the pledge from you. People come to you by migrating; you do not go to them by migrating. By the One in Whose hand is my soul, whoever loves the Ansar will meet Allah and Allah will meet him in such a way that Allah Himself loves him. Whoever harbors hatred against the Ansar will meet Allah and Allah will meet him in such a way that Allah Himself hates him.
