"O' Allah, sal ala Muhamed wa ala aal Muhamed and curse the two idols of Quraysh (Abu Bakr and Omar), its (Quraysh's) two sorcerers, its two tyrants, its two liars, and their two daughters (Aysha and Hafsah) who (Abu Bakr and Omar) disagreed with your order, denied your revelation, rejected your goodness, disobeyed your messenger, altered your religion, tampered (harafa) with your Book (Al-Quran), loved your enemy, rejected your lovers, suspended your verdicts, invalidated your orders, did not believe in your proves, antagonized your lovers, patronized your foes, ruined your country, and corrupted your slaves, O' Allah curse them both, their followers, their lovers, their people, their adherents, their partisans, their disciples ............."
