The people of the Days of Ignorance engaged in many practices which the Law of Islám later confirmed. They would not take in marriage both a mother and her daughter, and the most shameful of acts in their view was to marry two sisters. They would stigmatize a man marrying the wife of his father, derisively calling him his fathers competitor. It was their custom to go on pilgrimage to the House at Mecca, where they would perform the ceremonies of visitation, putting on the pilgrims dress, practicing the circumambulation, running between the hills, pausing at all the stopping-places, and casting the stones. It was, furthermore, their wont to intercalate one month in every three-year period, to perform ablutions after intercourse, to rinse out the mouth and snuff up water through the nostrils, to part the hair, use the tooth-stick, pare the nails and pluck the armpits. They would, likewise, cut off the right hand of a thief.
Can one, God forbid, assume that because some of the divine laws resemble the practices of the Days of Ignorance, the customs of a people abhorred by all nations, it follows that there is a defect in these laws? Or can one, God forbid, imagine that the Omnipotent Lord was moved to comply with the opinions of the heathen? The divine wisdom takes many forms. Would it have been impossible for Muammad to reveal a Law which bore no resemblance whatever to any practice current in the Days of Ignorance? Rather, the purpose of His consummate wisdom was to free the people from the chains of fanaticism which had bound them hand and foot, and to forestall those very objections which today confuse the mind and trouble the conscience of the simple and helpless.
Some, who are not sufficiently informed as to the meaning of the divine Texts and the contents of traditional and written history, will aver that these customs of the Days of Ignorance were laws which had come down from His Holiness Abraham and had been retained by the idolaters. In this connection they will cite the Quránic verse: Follow the religion of Abraham, the sound in faith.17
