Does tasting the dish break the fast? Please explain with evidences.
What breaks the fast is eating, drinking and sexual intercourse. Allah commands:
“(…) Eat and drink, until the white streak (of light) in the direction of the red streak of light (fajr) is clearly distinguishable by you from the black streak (of land in that direction). Then, complete the fast till nightfall. Do not have intercourse with your wives while you continue to seclude yourselves in the places of prostration to God. These are the bounds set by God; do not approach them! Thus, God explains His verses to the people so that they may protect themselves.” (Al-Baqarah 2:187)
