Hazrat Abu Al-Ahwas says that when a beggar comes to you and he intends to pray, or he said (the narrator is in doubt) he intends to perform prayer, then if you have the ability, give charity. Indeed, Allah Almighty has said, "Certainly, he has succeeded who purifies his soul and remembers the name of his Lord and prays." And if he has the ability to give charity before the prayer, then he should give charity.
