Sayyidatuna Ayeshah Siddiqah (Radi Allahu Ta'ala Anha) reported that the Beloved Prophet (SallAllahu Alayhi wa Sallam) said,
"There is a bridge upon Hell that is narrower than hairline and sharper than the edge of sword, it has iron hooks and clips that shall be gripping those whom Allah would will. People will pass over it, some within wink of an eye, some like flash, some like wind and some shall pass similar to the best (type of) horses and camels and the Angels will be pronouncing, ‘O Rab! Pass them safely, O Rab! Pass them safely.’ Some Muslims will win deliverance, some will get injured, some shall upend and some shall fall into the Hell on their faces." [Musnad Imam Ahmad, Vol. 9, Page 415, Hadith 24847]
The renowned commentator of the Holy Quran, Mufti Ahmad Yar Khan Na'eeimi (Alayhir Rahmah) has commented about the passers-by of the bridge of Sirat that the difference in their pace will be in accordance with their level of pious deeds and devotion i.e. their pace will be an index of their deeds and devotion. In this context, it is stated in "Ashi'atul Lam'aat" that pious deeds are the cause of pace and the merciful benevolence of the Holy Prophet (SallAllahu Alayhi wa Sallam) is the kernel of this pace. The more one is closer to the Holy Prophet (SallAllahu Alayhi wa Sallam) the more he picks the pace. [Mira'at al-Manajih, Hawd-o-Shafa’at ka Bayan, Vol. 7, Page 474]
