LessonsTafkhīm and Tarqīq — Alif, Divine-Name Lām and RāʾQuiz

The lām in Allāh is emphatic when preceded by fatḥah. Examples include وَاللّٰهِ and, in connected recitation, قَالَ اللّٰهُ.
This is a special rule of the divine name, not a rule making every Arabic lām heavy. Keep it a clear lām with a fuller resonance, avoiding exaggeration or distortion of adjacent sounds.
The book’s second case is ḍammah before the divine name. In رَفَعَهُ اللّٰهُ, the preceding “hu” ends with ḍammah, so the lām of Allāh is read emphatically in connected recitation.
Both fatḥah and ḍammah produce this heavy lām. Look at the connected reading context rather than assuming the word has one unchanging sound regardless of what precedes it.
