Wa alykum wa salam brother Ilker
Your welcome brother.
I agree of course that "saba" could be a literal meaning of seven.
However in the verse 15:87 what is the seven
"oft-repeated" that is MENTIONED IN the Quran? Surah Fateha is mentioned once as a whole surah/chapter.
This verse is not saying that us human's are often repeating the seven/several mentioned verses of the Surah Fateha.
It doe NOT mention verses at all. From my humble perspective this verse is regarding the seven/several often/repeated concepts or themes that are contained in the Quran.
For example God reminds us constantly and often in the Quran about believing in ONE GOD, that we should become or remain righteous, we should pray, give zakat, charity, we should do good deeds, and follow the Quran, etc.
15:87
"And certainly, We have given you seven/several of the oft-repeated (Arabic: saba'an minal-mathani) and the great Quran"It is reasonable and logical and a blessing and mercy from our Lord that He has given us Surah Fateha of course so we may recite it and ask of the right way from our Lord. But that's a different topic than what the verse 15:87 is really speaking about
