Starting with Wasl + Two Hamzas + Tashil + Naql

(1) Starting with Wasl Hamza (Hafs):

• "Al" article → Fathah: الْحَمْدُ starts as أَلْحَمْدُ
• Ten nouns → Kasrah: ابْن starts as إِبْن
• Verb with kasrah-3rd → Kasrah: اضْرِبْ → إِضْرِبْ
• Verb with fathah-3rd → Kasrah: اذْهَبْ → إِذْهَبْ
• Verb with dammah-3rd (essential) → Dammah: اقْتُلْ → أُقْتُلْ
• Verb with dammah-3rd (accidental) → Kasrah: امْشُوا → إِمْشُوا

(2) Two Hamzas Meeting:
In one word: Second silenced hamza replaced by Madd letter matching first's vowel:
أَأْدَم → آدَم | إِئْمَان → إِيمَان | أُؤْتِيَ → أُوتِيَ
From two words: Both pronounced (Hafs). Example: جَاءَ أَجَلُهُمْ

(3) Tashil (only place in Hafs):
"ءَأَعْجَمِيٌّ" in Surah Fussilat 44.
The second hamza is softened between hamza and alif. Hafs has two valid modes: tashil (preferred) and tahqiq.

(4) Naql (only place in Hafs):
"بِئْسَ الِاسْمُ" (Hujurat 11).
The kasrah of the dropped wasl-hamza is transferred to the Lam. Two modes: naql (preferred) and no-naql.
