And when you have finished your prayer, remember Verily, for all believers prayer is indeed a sacred duty linked to particular times (of the day). Surah Hud, 11:114 وَأَقِمِ الصَّلاَةَ طَرَفَيِ النَّهَارِ وَزُلَفًا مِّنَ اللَّيْلِ إِنَّ الْحَسَنَاتِ يُذْهِبْنَ السَّـيِّئَاتِ ذَلِكَ ذِكْرَى لِلذَّاكِرِينَ Wa ‘aqi-mis-Salaata tarafa-yin-nahaari wa zulafam-minal-layl: ’in-nal hasanaati yuz-hibnas-say-yi-’aat: zaalika zikraa liz-zaa-kiriin: 114.

These verses gives the ordinance about the five times of the prescribed daily prayers. This is another clear evidence about the fallacy in the claim of ‘Hasbuna Kitaballah’ .
The verse only gives the timing of the prayers while the details as to how they should be conducted and with what recitals of the passages of the Holy Qur’an, i.e. the wording of the prayers, we have to get from the Holy Prophet (S). This fact clearly indicates that any heavenly scripture, particularly the Holy Qur’an, independent by itself without the guidance from the Apostle of God, can never be sufficient to guide any one right.
