The right of your two legs is that you walk not with them toward that which is unlawful to you. You have no escape from standing upon the narrow bridge (al-sirat [over hell]), so you should see to it that your legs do not slip and cause you to fall into the Fire.
وَأَمَّا حَقُّ رِجْلَيْكَ فَأَنْ لا تَمْشِي بهِمَا إلَى مَا لا يَحِلُّ لَكَ فيهما، تقف على الصراط فانظر أن لا تزل بك فتتردى في النار.
