Let us have a look at some examples. Both – ب and the preposition مِنْ – can be used to give emphasis. Notice that the word which comes after بِ or مِنْ has to be مَجْرُور (majrour).
The letter ب (bi)
|Travelling is not difficult at all.|
لَيْسَ السَّفَرُ بِصَعْبٍ
|Allah is the best protector!|
كَفَى بِاللَّهِ وَكِيلًا
Note: The verb كَفَى basically means to be enough. However, it can also mean to protect; to spare. It is used without a preposition. The preposition ب here is used to emphasize.
The preposition مِن (min)
There has to be a singular اِسْم (noun) after it. Notice that there is no difference in meaning whether the sentence is written with or without مِنْ – it is just the emphasis!
|Nobody came to me.|
ما جاءَنِي مِنْ أَحَدٍ
