Those who establish prayers and are spending from whatever We have bestowed them.
To get a response for prayers and to accept deeds, two conditions are provided as explained in verses 2: 186 and 274. The Best Bounty is Adhikr which is the Prosperity. It is told in verse 102: 8 that you will be questioned about all favors you are bestowed with. It is told in verse 93: 11, then you speak about the favor of Lord. That means you propagate Adhikr which is the Mercy, Bounty, Food, Cloth, and Sight of the human soul. And it is told in verse 73: 11 to leave Me and those who are rejecting the Truth; grant chance to enjoy for a little to them who are bestowed with favors. The mode of prayer of Messenger Muhammad at the age of 45 was a single prolonged prostration as explained in verses 7: 205-206. See explanation 2: 2-5; 7: 157-158.
