Kitab-i-Iqan — Paragraph 43
Source (Persian)
حال به چشم علم اليقين و جناحَی عين اليقين به صراط حقّ اليقين قدم گذار، "قل اللّهُ ثُمَّ ذَرهُم فِی خَوضهِم يَلعَبُونَ" تا از اصحابی محسوب شوی که می فرمايد: "إنَّ الَّذينَ قَالُوا رَبُّنَااللّهُ ثُمَّ اسْتَقَامُوا تَتَنَزَّلُ عَلَيهِمُ المَلائِکَةُ." تا جميع اين اسرار را به بَصَر خود مشاهده فرمائی.
Translation
And now, with fixed gaze and steady wings enter thou the way of certitude and truth. “Say: It is God; then leave them to entertain themselves with their cavilings.” Thus, wilt thou be accounted of those companions of whom He saith: “They that say ‘Our Lord is God,’ and continue steadfast in His way, upon them, verily, shall the angels descend.” Then shalt thou witness all these mysteries with thine own eyes.
