The condition's verb: the first verb after the adat — jazmed by it when the tool is a jazima: إِن تَنصُرُوا۟.
Classical definition
فِعْلُ الشَّرْطِ هُوَ الفِعْلُ الأَوَّلُ بَعْدَ أَدَاةِ الشَّرْطِ، يُجْزَمُ إِنْ كَانَتِ الأَدَاةُ جَازِمَةً.
“The verb of the condition is the first verb after the conditional particle; it is jazmed if the particle is a jazima.”
(بتصرف من ابن هشام)

Understand it

Every conditional construction carries two verbs, and this is the opening one — the hypothesis itself. After إِنْ، مَنْ، مَا، مَهْمَا and the other jazim tools it stands in jazm (تَنصُرُوا۟ with its nun gone); after إِذَا and لَوْ it keeps its normal form, and a madi in this slot (إِن جَآءَكُمْ) sits in mahall jazm. Its partner, the jawab, then completes the bargain — see fi'l/jawab al-shart entries for the pairing rules.

How to spot it
Recognition test
The verb immediately after any adat shart: fi'l al-shart. With a jazima expect sukun, a dropped nun, or a dropped weak letter; a past verb there is locally jazmed.
In the Qur'an
وَإِن تَعُدُّوا۟ نِعْمَتَ ٱللَّهِ لَا تُحْصُوهَآ
An-Nahl 16:18 — “And if you tried to count Allah's blessings, you could never number them”
تَعُدُّوا۟ is the fi'l al-shart — jazm shown by the dropped nun after إِن.
