49 Preface لا يَسأَمُ الإِنسانُ مِن دُعاءِ الخَيرِ وَإِن مَسَّهُ الشَّرُّ فَيَئوسٌ قَنوطٌYusuf AliMan does not weary1 of asking for good (things), but if ill touches him, he gives up all hope (and) is lost in despair.Not only is man prone to doubts and speculations in matters beyond his ken, thus disturbing the even tenor of his spiritual life: he is apt to run into opposite extremes in his daily experiences in this life. He is always hankering after the good things of this life. They are not all good for him. If he receives a little check, even though it may be to bring him to his bearings and turn his thoughts to higher things, he is apt to fall into despair.
