وَ سَأَلَ رَجُلٌ أَمِيرَ اَلْمُؤْمِنِينَ عَلَيْهِ اَلسَّلاَمُ فَقَالَ لَهُ: يَا اِبْنَ عَمِّ خَيْرِ خَلْقِ اَللَّهِ تَعَالَى مَا مَعْنَى رَفْعِ يَدَيْكَ فِي اَلتَّكْبِيرَةِ اَلْأُولَى فَقَالَ عَلَيْهِ اَلسَّلاَمُ «مَعْنَاهُ اَللَّهُ أَكْبَرُ اَلْوَاحِدُ اَلْأَحَدُ اَلَّذِي «لَيْسَ كَمِثْلِهِ شَيْءٌ» لاَ يُلْمَسُ بِالْأَخْمَاسِ وَ لاَ يُدْرَكُ بِالْحَوَاسِّ.
A man asked The Commander of the Faithful Imam Ali ibn Abi Talib (a.s) saying: "O’ son of the cousin of the best of Allah’s (swt) creation, what is the meaning of raising your hands in the first Takbir (opening glorification of Allah (swt))?" He (a.s) replied: "It signifies that Allah (swt) is the Greatest, the One, the Unique, Who 'there is nothing like unto Him.' He cannot be perceived by the senses nor touched by the limbs."
