وكتبنا له في اﻻلواح من كل شيء موعظة وتفصيﻼ لكل شيء
And We wrote for him on the Tablets the exhortation all things and the explanation for all things:
Allah stated that He has written lessons and exhortation for all things and explanations for all things on the Tablets.
It was said that in the Tablets, Allah wrote advice and the details of the commandments for lawful and prohibited matters. The Tablets contained the Tawrah, that Allah described;
ولقد ءاتينا موسى الكتب من بعد ما أهلكنا القرون اﻻولى بصاير للناس
And indeed We gave Musa -- after We had destroyed the generations of old -- the Scripture as an enlightenment for mankind. (28:43)
It was also said that Allah gave Musa the Tablets before the Tawrah, and Allah knows best.
Allah said next,
فخذها بقوة
Hold unto these with firmness,
be firm on the obedience,
وأمر قومك يٲخذوا بٲحسنها
and enjoin your people to take the better therein.
Sufyan bin Uyaynah said, "Abu Sa`d narrated to us from Ikrimah from Ibn Abbas that;
"Musa, peace be upon him, was commanded to adhere to the toughest of what was ordained on his people.''
Allah's statement,
سٲريكم دار الفاسقين
I shall show you the home of the rebellious,
means, you will witness the recompense of those who defy My order and deviate from My obedience, the destruction, demise and utter loss they will suffer
