When the revenues of Bahrain arrive, I shall give you this much and this much and this much

Jābir ibn ‘Abdullāh (may Allah be pleased with him) says in this Hadīth that the Prophet (may Allah's peace and blessings be upon him) promised to give him a plentiful amount of the money that would come from Bahrain. The money came during the caliphate of Abu Bakr, after the Prophet had passed away. Abu Bakr asked those whom the Prophet had promised to give gifts or to whom he owed things to come over.

Indeed, the Prophet (may Allah's peace and blessings be upon him) might have purchased something from someone and owed him the price, or promised to give someone a certain grant. Jābir went to Abu Bakr and told him that the Prophet said that he would give him a certain amount when revenues came from Bahrain. Abu Bakr told him: 'Take.' So he scooped from the money with both hands and counted it, finding it to be five hundred. So Abu Bakr told him: "Take twice as much,"

because the Prophet (may Allah's peace and blessings be upon him) said: "This much and this much and this much", meaning three times. Thus Abu Bakr fulfilled the Prophet's promise to Jābir.
