وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، وَمُحَمَّدُ بْنُ بَشَّارٍ، قَالَ زُهَيْرٌ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ شُعْبَةَ، عَنْ قَتَادَةَ، عَنْ سَالِمِ بْنِ أَبِي الْجَعْدِ، عَنْ مَعْدَانَ بْنِ أَبِي طَلْحَةَ، عَنْ أَبِي الدَّرْدَاءِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ أَيَعْجِزُ أَحَدُكُمْ أَنْ يَقْرَأَ فِي لَيْلَةٍ ثُلُثَ الْقُرْآنِ ‏" قَالُوا : وَكَيْفَ يَقْرَأْ ثُلُثَ الْقُرْآنِ ؟ قَالَ : " قُلْ هُوَ اللَّهُ أَحَدٌ تَعْدِلُ ثُلُثَ الْقُرْآنِ " ‏.‏

Hadith Commentary

This noble hadith from the Messenger of Allah (peace be upon him) reveals the immense weight and significance of Surah al-Ikhlas in the divine scales. When Allah divided the Qur'an into three portions, He designated this surah as equivalent to one-third of the entire Qur'an. This is not in terms of textual quantity, but in spiritual substance and theological weight.

Surah al-Ikhlas contains the pure essence of Tawhid - the absolute Oneness of Allah. It comprehensively establishes Allah's unique attributes: His eternal existence, His self-sufficiency, His being without equal or offspring, and His absolute perfection. Since the Qur'an's primary purpose is to establish Tawhid, this surah encapsulates that fundamental message in its most concentrated form.

The recitation of this surah thus carries the reward of reciting one-third of the Qur'an, making it particularly valuable for travelers and those with limited time for lengthy recitation. This demonstrates Allah's mercy in providing abundant rewards through concise yet profound portions of revelation.

Scholarly Insights

Imam al-Nawawi comments that this hadith indicates the superiority of Surah al-Ikhlas and that its recitation earns the reward equivalent to one-third of the Qur'an. This extraordinary merit should encourage Muslims to frequently recite and reflect upon this chapter.

Ibn al-Qayyim explains that the Qur'an comprises three essential themes: commandments, stories of previous nations, and the description of Allah's names and attributes. Surah al-Ikhlas comprehensively covers the third theme - the divine attributes - thus earning its unique status.

This teaching particularly benefits travelers who may find it challenging to complete the entire Qur'an during journeys, yet can attain substantial reward through the frequent recitation of this concise yet weighty surah.
