In «الَّذِي أَطْعَمَهُمْ», a madd yāʾ ends one word and hamzah begins the next. Connecting them produces madd munfaṣil.
The next word also has a sākin emphatic ṭāʾ. Preserve its emphatic character; do not replace it with ordinary tāʾ. Being sākin does not make ṭāʾ a qalqalah letter.
If one stops after «الَّذِي», there is no cross-word meeting of madd and hamzah, so the separate madd rule is no longer active.
