Shama-il Tirmidhi Chapter 046, Hadith Number 003 (315).

Anas Radiyallahu 'Anhu reports: "Rasulullah Sallallahu 'Alayhi Wasallam visited the sick, attended funerals, rode on donkeys, accepted the invitations of slaves. On the day of the battle of Banu Qurayzah, he rode on a donkey, the reigns of which were made of date palm leaves. On it was also a saddle made of date palm leaves".

Commentary
In Arabia, there is special type of donkey, which is bigger than the local (Indian) mules. They run faster than the ordinary ponies. Two or three people can easily ride them. They are better than the ordinary local (Indian) horses. It is possible that these' donkeys existed in the time of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam. It is regarded as an inferior class of conveyance than that of horses. The object here is to show that Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam despite being of such a high status, and who possessed the leadership of both worlds did not feel belittled by riding a donkey. In the same manner, he visited the sick, be that person a respectable or an ordinary person. He even visited the sick non-Muslims. A Jewish lad used to attend the assemblies of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam. At times he assisted in some work too. When he became ill, Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam went to visit him. It was his last moments. Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam fulfilled his duties of kindness towards him, and presented to him the Message Islaam. The lad looked at his father, the father signalled his agreement. He accepted Islaam. Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam thanked Allah, as only Allah is worthy of hamd, who had saved this lad from the punishment of hell through him. Not only this, Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam also went to visit the leader of the hypocrites, 'Abdullah bin Ubay, when he became ill, whereas, he had troubled and harassed Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam many a time. In this manner we find in the ahaadith that he attended the funerals of many ordinary people.
