Shaykh Ibn ‘Uthaimeen said:
Among the causes that bring about increase in one’s imaan is having knowledge of Allah’s names and attributes. Whenever the slave increases in awareness of them, of their implications and effects, then imaan in His Rabb will [consequently] increase, as well as love and veneration of Him. Likewise, contemplating over the universal and legislative signs, whenever the slave observes them, pondering over their amazing power and their superb wisdom (of Allah demonstrated within them), then his imaan will without doubt increase.
