Information regarding Hazrat Ali

Question

Assalamualaikum
Can you give the reference for the story of Ali RA where he spares a man that spat on him because of the change of intention. The man embraces Islam and brings 70 others.
Can you give references of our beloved Prophet SAW giving dawat door to door or going to the people? brothers were asking for proof to the tablighi brothers via reference of door to door dawat?
Jazakallah

Tabraani as quoted in Majmau's Zawaaid, Vol 6 Pg 21. // Bidayah wa Nihayaah Vol 3 Pg 138, and Vol 3 Pg 142 // Isabah Vol 1 Pg 275. // Vol 4 Pg 312, Abu Nu'aym in his Da'aail Pg 96-105 // also our work 'Tabligh Made Easy - Pg112'
The first part of the story is correct not the second.
