It seemed like a burden which was greater that what their soul could bear but Allah is the Master plan.
The story of Ibrahim, Sarah, Hajar, and Ismail taught me a lot of things
Faith, Obedience, Trust and Hardwork.
When the workload, relationship and life looks too hard, remember Ibrahim was thrown into the fire, Ismail was about to be sacrificed by his father, Sarah had given up on having a child, Hajar was left with her little boy in the barren land.
Did He not cool the fire for Ibrahim? Did He not replace sacrificing Ismail with a ram? Did He not bless Sarah with Ishaq? Did He not provide water(Zamzam) for Hajar and Ismail in a barren land.
Having challenges? Don't give up, remember we shall all be tested. Our Lord! Lay not on us a burden greater than what we have the strength to bear.
