Sahih Muslim Book 4, Hadith Number 1492.

Chapter : The prayer of travellers and its shortening.

‘Abd al-Hamid reported: I heard ‘Abdullah b. al-Harith say: ‘Abdullah b. ‘Abbas addressed us on a rainy day, and the rest of the Hadith is the same, but he made no mention of Jumu’a prayer, and added: He who did it (who commanded us to say prayer in our houses), i.e. the Apostle of Allah (may peace be upon him), is better than I.
