Hadith: How to catch-up with charity by rich people

The Prophet Muhammad's (peace be upon him) companions once said to him: "The rich achieve the highest degrees of prestige and permanent pleasures (in this life and the life to come)." The Prophet asked: "How is that?" His companions replied: "The rich pray as we pray, and strive in God's Cause as we do, and spend from their surplus wealth in charity, while we have no wealth (to spend)." The Prophet then said: "Shall I not tell you a deed, by doing which, you will catch up with those who are ahead of you and supersede those who will come after you…That deed is to recite 'glory be to God' ten times, and 'praise be to God' ten times, and 'God is great' ten times after every prayer."
