Aisha (may Allah be pleased with her) said: I used to hear the Prophet (peace be upon him) mostly supplicates with: ‘O Changer of the hearts, make my heart firm upon Your religion.’ So I said: “O Messenger of Allah, why do you supplicate so frequently: ‘O Changer of the hearts, make my heart firm upon Your religion.’ He said: ‘Verily, there is no human being except that his heart is between Two Fingers of the Fingers of Allah, so whomsoever He wills He makes steadfast, and whomever He wills He causes to deviate[1].’”
(… بَعْدَ إِذْ هَدَيْتَنَا …) (…after You have guided us …): Guidance comes from Allah (swt):
{وَلَٰكِنَّ اللَّهَ يَهْدِي مَن يَشَاءُ}
(but Allah guides whom He wills.) (Al-Qasas: 56)
{ إِنَّ هَٰذَا الْقُرْآنَ يَهْدِي لِلَّتِي هِيَ أَقْوَمُ}
(Indeed, this Qur’an guides to that which is most suitable.) (Al-Israa: 9)
and the Sunnah of the Messenger of Allah (saws):
{ وَإِنَّكَ لَتَهْدِي إِلَىٰ صِرَاطٍ مُّسْتَقِيمٍ}
(And indeed, [O Muhammad], you guide to a straight path -) (Ash-Shura: 52)
(… وَهَبْ لَنَا مِن لَّدُنكَ رَحْمَةً…) (…and grant us from Yourself mercy …): ‘grant us’ because mercy is a grant by Allah (swt) and not a matter of right for you. The major characteristic of the religion of Islam is mercy because the Almighty says:
{وَمَا أَرْسَلْنَاكَ إِلَّا رَحْمَةً لِّلْعَالَمِينَ}
(And We have not sent you, except as a mercy to the worlds..) (Al-Anbiyaa: 107)
Our religion, then, is the religion of mercy to mankind, animals, plants, and all creatures. How come a religion of mercy whose Lord is the Compassionate and the Merciful, and whose Prophet is a mercy to all worlds make Muslims a source of killing, evil, harm, and all vices in the society. Never. How can we change Islam from a religion of mercy, a heavenly gift, and a Prophet described by the Almighty as:
{وَإِنَّكَ لَعَلَىٰ خُلُقٍ عَظِيمٍ}
(And indeed, you are of a great moral character.) (Al-Qalam: 4)
to crime and murder?
