National MARIAM Conference: Imam Faheem Shuaibe "Temperament Types In Marriage"

17: 84. Say: "Everyone acts according to his own disposition: but your Lord knows best who it is that is best guided on the Way."

4: 10. He set on the (earth) Mountains standing firm high above it and bestowed blessings on the earth and measured therein all things to give them nourishment in due proportion in four period in accordance with (the needs of) those who seek (sustenance).

The Prophet then said, "The descendants of Adam have been created in various categories. Some are born believers and live and die as believers; some are born infidels and live and die as infidels; some are born believers and live as believers, but die as infidels; some are born infidels and live as infidels, but die as believers."

It is said that he mentioned anger, saying, "Some are (1) swift to anger and swift to cool down, the one characteristic making up for the other; some are (2) slow to anger and slow to cool down, the one characteristic making up for the other; but the best of you are those who are (3) slow to anger and swift to cool down, and the worst of you are those who are (4) swift to anger and slow to cool down."
