Shama-il Tirmidhi Chapter 44, Hadith Number 5 (309).
‘Aayeshah Radiyallahu ‘Anha reports: “Rasulullah Sallallahu ‘Alayhi Wasallam kissed the forehead of ‘Uthmaan bin Maz’oon after his death. At that time tears were flowing from his eyes”.
This great Sahaabi was a foster brother of Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam. He was the thirteenth person to accept Islaam in its early stages. He first migrated to Abyssynia then to Madinah. He was very pious and devoted. At the time when it was still lawful to drink intoxicants, he had already abstained from imbibing it, He was the first among the Muhaajireen to pass away. He passed away in Sha’baan in the second year hijri and was buried in the Jannatul Baqi.
