Notes (Tafseer)

5502. Allah's Appreciation and Forbearing Kindness can reach so far beyond our merits, because (1) His universal knowledge comprehends hidden motives, which others cannot see in us; (2) His power is so great that He can afford to reward even the unworthy; and (3) His Wisdom is so great that He can turn even our weakness into our strength.
