@Karim @government @Abdalla @Poets @Dalmoor This thread should be rebived. I say we ask questions on smaller differences in different ayahs.
I'll start
Wa akhada alladiina dalamu sayxatu
Wa akhadati alladiina dalamu sayxatu
Falamma jaa amruna
Walamma jaa amruna
From Surah Hud
It would be very interesting if you guys would mention how you differ between those small differences. I, for example, differ the two I have highlighted from your example by remembering that there are two of each in Suurah Huud, i.e. they are four in total. The ones that begin with a waaw, "Walammaa", are the first of the four and the last of the four. Therefore, the two "Falammaa" beginning with a faa, are in the middle (the stories of Saalix and Ibraahiim).
Another example is the verses that begin with "Innalladhiina aamanuu walladhiina haaduu..." that, if I recall correctly, are three verses (Baqarah, Maa'idah, and Xajj). I differ between them by remembering that Wan-Nasaara is the first word after Haaduu in the first instance (i.e. Baqarah), which I remember by mentioning the closest to the Jews (the christians, also ahlul kitaab). For the rest of verses the Was-Saabi(u/ii)n is the word following "Haaduu". And so forth.
I am really curious how you do it. There are some "Mutashaabihaat" that I have learnt so well that I do not mistake them, but I need to have a present mind to not mistake most of them.
@Qarboosh may also want to participate.
I will in shaa Allah post the verses with subtle differences soon in shaa Allah that I have put to mind their differences.
