"اعبد الله لا تشرك به شيئا وأقم الصلاة المكتوبة وأد الزكاة المفروضة وحج واعتمر وصم رمضان وانظر ما تحب ¤ للناس أن يأتوه إليك فافعله بهم وما تكره أن يأتوه إليك فذرهم منه"
The Prophet (peace and blessings be upon him) said:
"Worship Allah, do not associate anything with Him, establish the obligatory prayer, pay the obligatory zakah, perform Hajj and Umrah, and fast in Ramadan. Look at the treatment you would like people to give you, and give them that same treatment; and the conduct you dislike for yourself, keep people safe from it too (that is, do not treat them that way)."
