The hilly and desert world of ancient Makkah was a natural training ground for the realization of God; the entire panorama of nature was an encouragement to man to remember Him. The only sign of human construction here, which claimed man’s attention, was the stone mosque, the Ka‘bah, built by Abraham and Ishmael. Here man could enter and engage in the remembrance of God. In this atmosphere, the children of Ishmael were miraculously provided with water from the Zamzam spring. Moreover, it was so arranged that they received sustenance (rizq) from produce which was not grown there. This was, in fact, a special arrangement to make them grateful. With the provision of extraordinary bounties, extraordinary feelings of gratefulness arise in man. This was the wisdom which was hidden in Abraham’s prayer that in the desert they should be provided with sustenance in the shape of fruits.
