Dua for concentration and understanding

When. Before study, before an exam, and after a lesson. Students are often taught this one on the first day, and it is short enough to say walking into the hall.

The words. Three requests, and the order is the argument. Infa'ni bima 'allamtani — benefit me by what You have taught me — comes first, and it is about knowledge already acquired. Before asking for more, the supplication asks that what is already there be made to work. Naf' is benefit in the practical sense: effect, not enjoyment.

Then 'allimni ma yanfa'uni — teach me what benefits me. The criterion is stated in the request itself; not everything learnable is worth learning, and the choosing is handed over.

Only third does zidni 'ilma appear, the same phrase as the Qur'anic supplication for increase. Placing it last makes it conditional on the two before it: increase, but of the kind just described.

What it implies about study. Knowledge that sits unused is treated as a real problem, not a neutral state. The first clause exists because a person can genuinely know something and be unchanged by it.

Common confusion. This is a longer, three-part supplication and not the same as Rabbi zidni 'ilma by itself, though the last words overlap. The short Qur'anic phrase asks for one thing; this asks for three, and the increase is the smallest of them.

In practice. Studying remains the work. Nothing in these words replaces the hours.
