The Prophet gave us seven commands and seven prohibitions. He commanded us to visit the sick, to follow funerals, to say ‘God have mercy on you’ when someone sneezes, to return salutations, to accept invitations, to help people to fulfil their oaths, and to help the wronged; and he forbade us gold rings, silk, thick brocade, embroidered silk, red stuffing placed on a saddle, Qassi garments (said to be cloth made of flax and raw silk which came from a place in Egypt called Qass between al-'Arish and al-Farama. Another suggestion is that the name is changed from qazzi and means silk.) and silver vessels. A version says drinking from silver vessels, for he who drinks out of them in this world will not drink out of them in the next.
He reported God’s messenger as saying, “A Muslim has six duties towards another Muslim.” When asked what they were he replied, “When you meet him salute him ; when he issues an invitation to you, accept it; when he asks your advice give it to him ; when he sneezes and praises God say, ‘God have mercy on you’; when he is ill visit him ; and when he dies follow him to the grave.”
Thauban reported God’s messenger as saying, “When a Muslim pays a sick visit to his brother Muslim he continues to gather the fruits of paradise till he returns.”
