What is the difference between "al-ʿuṣbah" (العصبة) and "al-ʿiṣābah" (العصابة), and between "al-mulk" (الملك) and "al-malakūt" (الملكوت)?

The difference between 'usbah (عُصبة) and 'isabah (عِصابة) is that an 'usbah refers to a group of men, numbering between ten and forty, while an 'isabah refers to a group of people, horses, or birds. As for al-mulk (المُلْك) and al-malakut (المَلَكوت), they share the same meaning, with al-malakut conveying an intensified sense of al-mulk.
