"Hadha min fadli Rabbi" (هَٰذَا مِن فَضْلِ رَبِّي) is an Arabic phrase from the Quran which translates to "This is by the grace of my Lord" in English.
This phrase expresses acknowledgment and gratitude for the blessings, grace, and favors bestowed by Allah. It reflects a deep sense of humility and recognition of Allah's generosity. The phrase is often used by Muslims to show thankfulness for good fortune and to acknowledge that all success and blessings come from Allah.
In the Quran, this phrase is notably spoken by Prophet Sulaiman (Solomon) as a recognition of the blessings given to him by Allah, showing his humility and gratitude despite his vast kingdom and power. It's a reminder for people to attribute their successes and gifts not to their own efforts alone, but to the grace and favor of Allah.
