Lesson

1. Conditional Sentences with إِنْ

إِنْ means if. It links a condition to the consequence that depends on it. إِنْ تَدْرُسْ تَنْجَحْ If you study, you will succeed. The studying is the condition. Success is the consequence. By the end, you will identify both parts and explain why both imperfect verbs are jussive.

2. The Two Parts

A conditional sentence has two connected parts. ● Condition (شرط): the event introduced by إِنْ. ● Answer of the condition / consequence (جوابِ شرط یا جزاء): what follows if the condition occurs. In إِنْ تَجْلِسْ أَجْلِسْ: Condition: تَجْلِسْ — you sit. Answer: أَجْلِسْ — I sit. The second action is understood in relation to the first.

3. Why Both Verbs Are Jussive

When both parts use imperfect verbs, إِنْ makes the condition verb jussive, and the answer verb is jussive as well. This jussive form is called Mudari Akhaff. Before the conditional construction: تَجْلِسُ — you sit; أَجْلِسُ — I sit. Inside it: إِنْ تَجْلِسْ أَجْلِسْ Both final dammahs become sukuns. Do not leave one verb nominative while making only the other jussive.

4. The Familiar Ending Rules Still Apply

The two verbs can show different visible jussive results because each follows its own ending group. ● Final sukun: تَدْرُسُ ← تَدْرُسْ and تَنْجَحُ ← تَنْجَحْ. ● Inflectional nun removed: يَجْلِسُونَ ← يَجْلِسُوا. ● No visible change with nun an-niswah: تَكْتُبْنَ ← تَكْتُبْنَ. So إِنْ يَجْلِسُوا نَبْدَأْ is correct: the first verb loses its inflectional nun, while the second ends in sukun.

5. Read the Condition and Its Answer

Read the first two examples by naming each part. إِنْ تَجْلِسْ أَجْلِسْ Condition: if you sit. Answer: I will sit. إِنْ تَضْرِبْنِي أَضْرِبْكَ Condition: if you strike me. Answer: I will strike you. In تَضْرِبْنِي, the attached نِي means “me.” The jussive sukun remains on بْ before that suffix.

6. Two Different Jussive Results

A conditional sentence can combine different ending groups. إِنْ تَنْصُرُوا اللَّهَ يَنْصُرْكُمْ If you support Allah's cause, He will help you. Condition verb: تَنْصُرُوا — its inflectional nun is removed. Answer verb: يَنْصُرْكُمْ — its final dammah becomes sukun. إِنْ تَرْحَمْ تُرْحَمْ If you show mercy, you will be shown mercy. Both verbs end in jussive sukun; the second is passive.

7. Translate the Relationship, Not Just the Words

A clear translation should preserve the if-then relationship. إِنْ تَفْتَحْ الْبَابَ أَدْخُلْ Condition: you open the door. Consequence: I enter. Idiomatic translation: If you open the door, I will enter. Urdu often uses اگر ... تو .... English normally uses if in the condition and expresses the consequence in the other clause.

8. Three Common Mistakes

Check meaning, clause role and verb ending separately. ● Do not translate إِنْ as “not yet”; that is لَمَّا. ● Do not call the first verb the answer; it states the condition. ● Do not write إِنْ تَجْلِسُ أَجْلِسُ here. With two imperfect verbs, both should show the jussive result: إِنْ تَجْلِسْ أَجْلِسْ.

9. A Four-Step Reading Method

Use these four steps for an إِنْ conditional with two imperfect verbs. 1. Find إِنْ and translate it as “if.” 2. Mark the first clause as the condition. 3. Mark the second clause as the answer/consequence. 4. Explain the jussive result on each verb according to its ending group. Then give one complete idiomatic translation that keeps the condition and consequence connected.
