وَلَسَوْفَ يُعْطِيكَ رَبُّكَ فَتَرْضَىٰ
And surely your Lord will give you, so that you will be satisfied. (الضحى: 5)
In la-sawfa, the lām strengthens the assertion and sawfa locates the giving in the future. In yuʿṭīka rabbuka, rabbuka functions as the agent and the addressed pronoun as object. The promise moves beyond refuting an anxiety to establishing a positive expectation.
Emphatic futurity suits the consolatory context. The verse does not list a set of specific gifts; an analyst should not invent one in order to fill the expression. The consequence, fa-tarḍā, is more important to its stated communicative force than conjectured details.
