Al-'Ankabut · Saba

Both state that Allah expands and restricts provision for whom He wills but 29:62 ends with 'bi kulli shay'in 'alim' while 34:36 ends with 'akthara al-nas la ya'lamun'.

Al-A'raf · Al-'Ankabut

The earthquake-destruction formula: 'the earthquake seized them and they became in their dwelling lying prone'; 7:78 is Thamud/Salih, 29:37 is Madyan/Shu'ayb; see also 7:91/29:37 and 7:78/7:91 (batch 6).

Al-A'raf · Al-'Ankabut

Both describe Madyan's destruction: 7:91 uses rajfa for Shu'ayb's people in Al-A'raf, 29:37 also uses rajfa for the same event in Al-Ankabut; completes the three-way set with 7:78/7:91 (batch 6) and 7:78/29:37.
