(20) And its bounty is from what was related by Ibn as-Sunee in ‘Amalul-Yawmi wal-Laylah (#71) from his statement said: “Whoever recites seven times every day upon entering the morning and upon entering the evening: Sufficient for me is Allah there is nothing worthy of worship except for Him, I place my trust in Him, He is the Lord of the mighty throne, Allah will suffice him with all of his concerns from those affairs of the Dunyaa (the affairs of this life) and the Hereafter.” And it was authenticated by Shu’ayb and ‘AbdulQaadir al-Arnaaoot in Tahqeequ Za’adil-Ma’ad (2/342).
