Oko iya eleko sermon,he/she who knows about Allah rahman, he/she have knew Allah.

Surah Fatir, Verse 31:
وَالَّذِي أَوْحَيْنَا إِلَيْكَ مِنَ الْكِتَابِ هُوَ الْحَقُّ مُصَدِّقًا لِّمَا بَيْنَ يَدَيْهِ إِنَّ اللَّهَ بِعِبَادِهِ لَخَبِيرٌ بَصِيرٌ

And that which We have revealed to you of the Book, that is the truth verifying that which is before it; most surely with respect to His servants Allah is Aware, Seeing.

Surah Fatir, Verse 33:
جَنَّاتُ عَدْنٍ يَدْخُلُونَهَا يُحَلَّوْنَ فِيهَا مِنْ أَسَاوِرَ مِن ذَهَبٍ وَلُؤْلُؤًا وَلِبَاسُهُمْ فِيهَا حَرِيرٌ

Gardens of perpetuity, they shall enter therein; they shall be made to wear therein bracelets of gold and pearls, and their dress therein shall be silk.

Surah Fatir, Verse 34:
وَقَالُوا الْحَمْدُ لِلَّهِ الَّذِي أَذْهَبَ عَنَّا الْحَزَنَ إِنَّ رَبَّنَا لَغَفُورٌ شَكُورٌ

And they shall say: (All) praise is due to Allah, Who has made grief to depart from us; most surely our Lord is Forgiving, Multiplier of rewards,
Surah Fatir, Verse 35:
الَّذِي أَحَلَّنَا دَارَ الْمُقَامَةِ مِن فَضْلِهِ لَا يَمَسُّنَا فِيهَا نَصَبٌ وَلَا يَمَسُّنَا فِيهَا لُغُوبٌ

Who has made us alight in a house abiding for ever out of His grace; toil shall not touch us therein, nor shall fatigue therein afflict us.
