Is it prohibited to wear qamīs, the hands of which come down to below the wrists?
This is not considered to from the isbāl (dropping of the thawb) which is ḥarām, if that is what the questioner has intended. The isbāl is only in regards to that which falls below the ankle. The Prophet Ṣallallāhu ʿalayhi wa sallam said: “That which falls below the ankles from the garment is in the fire” i.e the companion of the garment. Reported by Bukhārī on the authority of Abū Hurayrāh raḍiyAllāhu ʿanhu
However it is befitting that the Muslim does not go beyond bounds in spending on himself, and it is prohibited to be wasteful in food, drink, clothing and all aspects.
وَالَّذِينَ إِذَا أَنفَقُوا لَمْ يُسْرِفُوا وَلَمْ يَقْتُرُوا وَكَانَ بَيْنَ ذَٰلِكَ قَوَامًا
And those whom when they spend are neither extravagant nor niggardly, but hold a medium way between those extremes.
وَلَا تُبَذِّرْ تَبْذِيرًا (٢٦) إِنَّ الْمُبَذِّرِينَ كَانُوا إِخْوَانَ الشَّيَاطِينِ
الإسراء: ٢٦ – ٢٧
But spend not wastefully your wealth in manner of a spendthrift, verily the spendthrifts are brothers of the devils.
Allāh ʿAzza wa Jalla knows best.
والحمد لله رب العلمين
