The invoking and supplicating of the Imam for the one who gives in charity

وَقَوْلِهِ: {خُذْ مِنْ أَمْوَالِهِمْ صَدَقَةً تُطَهِّرُهُمْ وَتُزَكِّيهِمْ بِهَا وَصَلِّ عَلَيْهِمْ إِنَّ صَلاَتَكَ سَكَنٌ لَهُمْ}.And the Statement of Allah تعالى: "Take Sadaqa (alms) from their wealth in order to purify them and sanctify them with it, and invoke Allah for them. Verily, your invocations are a source of security for them..." (V.9:103)
