Imām Ibn al-Qayyim (d. 751 AH) said:
“The guidance [being invoked in Sūrah al-Fātiḥah] has another level, which is its final level. This is the guidance on the Day of Judgement to the path of Jannah. For there is a path [ṣirāṭ] that reaches Jannah.
Whomsoever is guided in this worldly life to the straight path of Allāh as espoused by His Messengers and His Books, will be guided [in the hereafter] to the straight path that leads to His Jannah—the place of His reward.
It is the degree of stability that the slaves [of Allāh] have on the path that has been set forth for them in this life that determines the stability of their feet on the ṣirāṭ that will be raised over Jahannam [in the hereafter]. Their strength of traversal on this worldly path will determine how they traverse that path [over Jahannam]. So, from among [the slaves of Allāh] are those who can move like lightning, others like the blink of an eye, others like the movement of wind, others like a strong rider, others like a fast run, others like a walk, and others like a crawl. From among them are those who are saved and those who are cast out. So, let every slave [of Allāh] look at his traversal of this [worldly] path to see how he will fare on that path [in the hereafter]. His steps here [in this dunyā] will be like his steps there [in the hereafter]. A befitting recompense [Allāh says]:
هَلْ تُجْزَوْنَ إِلَّا مَا كُنتُمْ تَعْمَلُونَ ﴿٩٠﴾
‘Are you recompensed except for what you used to do?’
Let him look also at the desires and confusions that impede his traversal on the straight path. They are like the hooks that surround the path [in the hereafter] that protect it and impede traversal on it. If the [desires and confusions] are plentiful and robust in this life, such will the [hooks] be in the hereafter [Allāh says]: ‘
وَمَا رَبُّكَ بِظَلَّامٍ لِّلْعَبِيدِ ﴿٤٦﴾
And your Lord is not ever unjust to [His] servants.’
