A dead date palm starts giving fruits
When the time for the birth of Hadhrat ‘Isa (May peace be upon her) drew close, his mother Hadhrat Maryam (May peace be upon him) approached a dry date palm with no dates on it. Allah Most High said:
And shake the trunk of the palm-tree toward thee, thou wilt cause ripe dates to fall upon thee. Surah Maryam (19:25)
It is mentioned in the verse that the moment Hadhrat Maryam (May peace be upon her) touched the trunk of the date palm, it started shedding fresh dates in her lap. For a dead tree to become green again, it takes time. A tree does not become fruit bearing in a few moments or a few hours. It cannot become green and cover itself with foliage and flowers.
A dead tree become green and fruit-bearing in just a moment is surely a miracle of the pious worshipper of Allah Most High.
