وَعَن يعلى بن مرَّة قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «حُسَيْنٌ مِنِّي وَأَنَا مِنْ حُسَيْنٍ أَحَبَّ اللَّهُ مَنْ أَحَبَّ حُسَيْنًا حُسَيْنٌ سِبَطٌ مِنَ الأسباط» رَوَاهُ التِّرْمِذِيّ
Translation

Ya'la b. Murra reported God's messenger as saying, "Husain pertains to me and I to him. May God love him who loves Husain! Husain is a grandson[*]."*Another possibility is `a tribe', meaning that he would have many descendants; but the translation above is more likely. Cf. Mirqat, 5:605.Tirmidhi transmitted it.
