Although several researchers have been interested in the issue of textual variation of hadith, few studies have been undertaken to determine statistically the date and the process of generation of hadith variants. This study seeks to present three initial mathematical models that approximate the processthrough which variantsof the whole hadithsrecorded in al-Bukhārī's Ṣaḥīḥ were generated, under the assumption that many of the recorded hadiths were intentionally or unintentionally (i. e., by error) reformulated once or more with almost the same probability since they first entered circulation. Namely, by counting Bn, i. e., the number of hadith groupsthat comprise n variants, we obtain a sequence (Bn). Notably, (Bn) formsapproximately a geometrical sequence with a common ratio of 0.63. Based on this finding, we can establish a recurrence formula containing two or three parameters that determines the numbersof hadithscompris ing a certain number of variantsat a certain point in time each. By setting these parameters to appropriate values, we can establish two models that closely approximate (Bn).

Kharoṣṭhī letters were used for almost five centuries in North-Western Indian subcontinent, from around the third century BCE until around the third century CE. Paleographical studies of Kharoṣṭhī letters have revealed gradual changes in letter forms over time. However, these letter forms have not always been used as a clue to determine dates of inscriptions, mainly because sometimes relatively old letter forms appear on newer inscriptions. As such, the study of letter forms as a potential indicator for dates has not been sufficiently used to clarify the history of the area. This paper proposes a way to deal with letter forms in order to use them as an indicator for the dates of inscriptions. While the presence or absence of each letter form has been a focus of scholars so far, this paper explores their ratio instead. There are varied forms for three Kharoṣṭhī letters : "s, " "e, " and "c." By counting each form of each letter on a particular inscription, the main form of each letter used on the inscription can be determined. In order to construct the chronology of the Kharoṣṭhī letter forms, inscriptions whose dates can be known are used. By evaluating ones whose authenticity is clear, we can assert that the main forms of these three letters actually changed with time. Furthermore, by analyzing others that have been purchased in modern markets and whose authenticity is unclear, we can suggest when the main forms changed. Through these steps, we can propose a chronology of Kharoṣṭhī letter forms where an inscription is assigned to one of six phases based on the combination of the three letters' main forms. The fact that similar changes in main forms of Kharoṣṭhī letters are also detected in manuscripts can be seen as a corroboration of the above results with inscriptions. We can conclude that Kharoṣṭhī letter forms can be a good indicator for the date of inscriptions, and also possibly manuscripts.

For Muslims lived inan y part of premodernIslamic world the Islamic law of succession served as a barrier to anattempt to keep family property intact, because it stipulated that equal shares should be given to those who were in equal relationship to deceased. Consequently, those who had an intention to keep the integrity of their inherited property had to have recourse to different ways to achieve their goal. One such way was jointly owning inherited property by heirs, whereas they received appropriate shares of the estate. In this case, if one of the joint owners died, his/her shares were inherited by his/her own heirs including sometimes those who had been outside the co-ownership for their not having the right of succession to the generator of the estate. By consulting the fatwa document which was produced in the early twentieth century Samarqand province of Russian Turkestan, and which records the case concerning the joint ownership of family property, the author offers following conclusions : first, the way of calculating the shares allocated to each one of the joint owners, as shown by the calculating tables attached to the document, completely agrees with the teachings found in al-Farā'id ̇ al-Sirājīya, the twelfth century Hanafite juristic work specially devoted to the law of succession and enjoyed prolonged popularity as a fundamental textbook for learning the method of calculating shares of succession. Second, as presented by similar fatwa documents from Russian Turkestan, through the inheritance of the shares held by deceased joint owners, the membership of co-owners could have been even conferred to the persons who were in relationship to the generator of the estate either through maternal line or by affinity, whereas they were prone to be excluded from or explicitly not entitled to inheritance according to the lslamic law.
