(Yoosuf) 12 : 67
وَقَالَ يَا بَنِيَّ لَا تَدْخُلُوا مِنْ بَابٍ وَاحِدٍ وَادْخُلُوا مِنْ أَبْوَابٍ مُتَفَرِّقَةٍ ۖ وَمَا أُغْنِي عَنْكُمْ مِنَ اللَّهِ مِنْ شَيْءٍ ۖ إِنِ الْحُكْمُ إِلَّا لِلَّهِ ۖ عَلَيْهِ تَوَكَّلْتُ ۖ وَعَلَيْهِ فَلْيَتَوَكَّلِ الْمُتَوَكِّلُونَ
And he said: "Oh my sons! You don't enter through one gate, but you enter through different gates, and I can't avail anything from you against Lord Allah; indeed the Judgment is with none except with Allah; upon Him I entrusted, and upon Him should entrust those who would entrust".
The Wise-Lord inspired Yaqoob to instruct his sons to enter Yoosuf through different gates so that Yoosuf can identify his brother Binyamin. Today, Adhikr-the Safeguard-is formed as the Book. So, whoever holdfasts It, he did holdfast Lord and is guided into the Straightpath as explained in verses 3: 101-102 and 5: 48. See explanation 2: 269; 9: 51 and 10: 60-61.
