"Then when there came the first of
the two promises (of Divine Punishment), We sent against you servants unto Us who were most powerful in warfare. Then
they penetrated the homes. Indeed it was a decree
executed."
(Surah Bani Israaeel, aayat 5)
"When the final promise(of Divine Punishment) came,
(it came) so that they could (the kuffaar) disfigure your faces and enter the Musjid (i.e.Musjidul Aqsa)as they had entered the first time, and so that they could utterly destroy whatever they overran."(Surah Bani Israaeel, aayat 8)
In these Qur'aanic verses, Allah Ta'ala refers to His punishment which He had inflicted on the Muslims of former times. The specific community referred to in these verses is Bani Israaeel. Two occasions of punishment are mentioned here. on both occasions Allah Ta'ala used the kuffaar to overwhelm, punish and humiliate the Muslims.

When a modernist Muslim criticizes the dress style and appearance of Rasulullah (sallallahu alayhi wasallam) and the Sahaabah, we in this age in which kufr preponderates, are not surprised. Immersed in the kufr concepts and liberalism of the western kuffaar, it is just natural and logical for modernists to denigrate every teaching of the Sunnah which conflicts with the tastes and hues of western culture.
