The Proofs of Tawhid for People of Understanding, their Characteristics, Speech, and Supplications

Allah said,

إِنَّ فِى خَلْقِ السَّمَـوَتِ وَالاٌّرْضِ

That human intentions and plans keep failing everywhere all the time is a matter of common experience. These cannot be called the prime movers and operators of this universal system. Therefore, the outcome of the deliberation into the creation of the heavens and the earth and into what has been created in them is, as wisdom dictates, living to know, obey and remember Allah. Anyone unmindful of it does not deserve to be classed as wise. Therefore, the Holy Qur'an has given the following sign of the wise:

الَّذِينَ يَذْكُرُ‌ونَ اللَّـهَ قِيَامًا وَقُعُودًا وَعَلَىٰ جُنُوبِهِمْ
