Divine wisdom in responding to doubt

إِذْ قَالَ ٱلْحَوَارِيُّونَ يَـٰعِيسَى ٱبْنَ مَرْيَمَ هَلْ يَسْتَطِيعُ رَبُّكَ أَن يُنَزِّلَ عَلَيْنَا مَآئِدَةً مِّنَ ٱلسَّمَآءِ ۖ قَالَ ٱتَّقُوا۟ ٱللَّهَ إِن كُنتُم مُّؤْمِنِينَ

[And remember] when the disciples said, "O Jesus, Son of Mary, can your Lord send down to us a table [spread with food] from the heaven?" [Jesus] said, "Fear Allāh, if you should be believers."
