O ye who believe! When ye consult the Messenger in private, spend something in charity before your private consultation. That will be best for you, and most conducive to purity (of conduct). But if ye find not (the wherewithal), Allah is Oft-Forgiving, Most Merciful. (12)
Tafsir
It was the intention of Almighty God that only those who wished to meet the Prophet for some really serious purpose, should be allowed to come into his presence, while those who only wasted time in useless talk should be kept away. So, it became the rule that when one intended to meet the Prophet Muhammad, he should first give alms in the name of God, and if one could not afford to do so, he should perform some other righteous deed. These injuctions were originally intended to apply to the Prophet, but even after the Prophet the same conduct will be required toward the leaders of the community, according to their status.
