Al-Baqarah · 2:40

40. O Children of the Prophet Jacob, remember the many blessings He gave you and be thankful for them. Fulfil your contract to Him, having faith in Him, His prophets and His sacred laws. If you fulfil your contract, He will fulfil His contract to you, as well as His promises to you of a good life on earth and a beautiful reward on the Day of Judgement. Fear Him alone and do not break His contract.
