@abdxshakur: Tranquility is not merely a sense of inner comfort. Rather, it is a cause for an increase in faith: “So that they may grow stronger in faith along with their present faith.” The more the heart is filled with tranquility, the greater its certainty in Allah becomes, along with better expectations of Him and steadfastness upon His command. Then Allah clarified the outcome of this tranquility and faith: “So that He may admit the believing men and believing women into Gardens under which rivers flow.” Tranquility is not only a temporary blessing in this world. It is also a path to the ultimate success in the Hereafter. O Allah, send down upon our hearts tranquility from You, increase us in faith through it, make us steadfast during trials, and grant us Your pleasure and Your Gardens through it.
