From Sahih Bukhari (Hadith 2157):
Narrated Jarir:I have given a pledge of allegiance to Allah's Messenger (ﷺ) for to testify that None has the right to be worshipped but Allah, and Muhammad is His Apostle, to offer prayers perfectly, to pay Zakat, to listen to and obey (Allah's and His Prophet's orders), and to give good advice to every Muslim
