Surah al-Kahf follows Surah al-Israa with which it is very closely related. According to Mawlana Amin Ahsan Islahi (1904-1997) almost every Surah has a twin. All Surahs are arranged in pairs. Like partners, not only are there similarities between them but they also complement each other. If there are gaps in one Surah, the other fills it. If something is hidden in one, the other manifests it. They shine like the sun and moon. In long Surahs we see these features in al-Baqarah and Ale ‘Imraan; in short Surahs we can observe them in the last two Surahs, numbers 113 and 114, which are collectively called al-Mu’awwidhtayn (the two Surahs in which Allah’s refuge from evil is sought). The Prophet (peace be upon him) used to recite them in pairs, for example Surah al Qiyamah in one ruku’ and al-Insaan in another, and similarly Surahs al-Saff and al-Jumuah and Surahs al-‘Ala and al-Ghaashiyah.
According to Mawlana Islahi, there are some exceptions about this pairing of Surahs, for example Surah al-Fatihah has no partner, being in itself the Introduction to the whole Quraan. Incidentally, one of the names of al-Fatihah is al-Kaafiyah indicating that it is self-suffiecient and does not need paiting. In some cases, a later Surah is the continuation of the preceding Surah or its appendix. For example Surah at-Tawbah is the continuation of Surah al-Anfaal and the same relationship exists between Surahs al-Mo’minoon and an-Noor.
According to Dr. Israr Ahmad, the relationship between al-Israa and al-Kahf is very close. Both are equal in length. Al-Israa has 111 verses while al-Kahf has 110. Al-Israa begins with SubhanAllah and al-Kahf starts with Alhamdolilah. Both these expressions of praise complement each other, as it is narrated in a hadith that SubhanAllah and Alhamdolilah fill up the whole of the balance (mizaan), or, fill up the whole (universe) that lies between the Heavens and the earth (Muslim).
There is a similiarity in their endings as well. The last two verses of both Surahs start with the word ‘qul’ (say):
Thus, there are four quls and their meanings are truly great. The penultimate verse of al-Israa mentions al-Asmaa al Husna and that of al Kah alludes to Kalamaat Rabbi (Words of my Lord).
The last verse of al-Israa prohibits committing shirk thus lowering His Status, whereas al-Kahf’s last verse forbids raising anyone to Allah’s status. The last two words of al-Israa are Kabbirhu Takbeera (so glorify Him in a manner worthy of His Glory; shown below). Hence, al-Kahf starts with alhamdolilah (praise be to Allah) and this praise is the most worthy expression of Allah’s Glory as they are the first words of Surah al-Fatihah.
There are several topics which are repeated in both Surahs but in a different manner. The story of the Prophet Adam (peace be upon him) and Satan is narrated in the sixth ruku’ of both Surahs (al-Israa verses 61-65 and al-Kahf verses 50-53).
