Qatādah (r) mentioned that Sa‘d Ibn Abī Waqqāṣ (ra) and Salmān al-Fārisī, the Persian, (ra) had a conflict with each other. Out of anger or frustration, Sa‘d (ra) said, ❝Tell me your lineage, O Salmān.❞ Salmān al-Fārisī, who was a non-Arab, replied: ❝I don’t have a Muslim father, but I am Salmān, the son of Islam!❞
When the news of this got to ‘Umar (ra), he met Sa‘d (ra) and said, ❝Tell me what your lineage is, O Sa‘d!?❞ Sa‘d (ra) realized his mistake in resorting to lineage as a card in his discussion with Salmān (ra). He replied: ❝I plead to you by Allah [to let me go], O leader of the believers!❞ However, ‘Umar (ra) insisted that Sa‘d mention his lineage.
After Sa‘d (ra) mentioned his lineage, ‘Umar Ibn al-Khaṭṭāb (ra) said, ❝Quraish knows that al-Khaṭṭāb was the most honorable of people in the pre-Islamic days, but even then I am ‘Umar, the son of Islam. I am the brother of Salmān, the son of Islam…❞ [al-Siyar]
Don’t let your lineage, your nationality, your race, your color, or your gender make you forget that you are, in fact, the sons and daughters of Islam.
