The conquests of Qutayba fall naturally into four periods:

1. 86/705: The recovery of Lower Tukhāristān;

2. From 87/706 to 90/709: The conquest of Bukhārā;

3. From 91/710 to 93/712: Consolidation of the Arab authority in the Oxus valley and its extension into Sughd;

4. From 94/713 to 96/715: Expeditions into the Jaxartes provinces.

The recovery of Lower Tukhāristān.

The first task before Qutayba was to crush the revolt of Lower Tukhāristān. In the spring of 86/705 the army was assembled and marched through Merv Rūdh and Tālaqān on Balkh. According to one of Tabarī’s narratives the city was surrendered without a blow. A second account, which, though not explicitly given as Bāhilite, may be regarded as such, since it centres on Qutayba’s brother and is intended to establish a Bāhilite claim on the Barmakids, speaks of a revolt amongst some of the inhabitants. This may perhaps be the more correct version, since we hear of Balkh being in a ruinous condition four years later (Tab. 1206. 1). The submission of Balkh was followed by that of Tīsh, king of Chaghāniān, who had probably cooperated with Mufaddal in the attack on Tirmidh the year before. His action was, it seems, inspired by a feud with the king of Shūmān and Ākharūn, in the upper valleys of the Surkhan and Penjab rivers, against whom he hoped to use the Arab troops in return for his assistance to them. Mufaddal had actually projected an expedition against Shūmān before his recall, and it was now carried out by Qutayba, who was perhaps the more ready to undertake it since it assured the safety of the southern approach to the Iron Gate. After the submission of the King Ghīslashtān, who was of Turkish blood, according to Yuan Chwang, Qutayba returned to Merv alone, leaving the army to follow under his brother Sālih, who carried out a number of minor raids on the way. It is obvious that, in spite of Balādhurī’s imaginative account, these raids must be located in the districts neighbouring on the Oxus. The readings in Tabarī’s narrative are, however, defective[43]. Having thus isolated Nēzak in Bādghīs, the heart of the revolt, Qutayba spent the winter months in negotiating with him through Sulaym “the Counsellor,” an influential Persian whose skill in conducting the most difficult negotiations proved more than once of the utmost value to Qutayba. Nēzak was persuaded to surrender and was conducted to Merv, where peace was concluded on condition that Qutayba would not enter Bādghīs in person. As a precautionary measure however the governor arranged that Nēzak should accompany him in all his expeditions. Thus for the moment at least, the danger of an outbreak in Khurāsān was averted, in a manner honourable to both parties, and the son of Pērōz took his way back to China to await a more favourable opportunity[44].

The Conquest of Bukhārā.

In the following year, Qutayba, first making sure of the crossings at Āmul and Zamm, opened his campaigns in Bukhārā with an attack on Paykand. From the expressions of Narshakhī, on whose history of this period we may place more reliance since his details as a rule fit in with and supplement the other histories, it can be gathered that the principality of Bukhārā was weakened by civil war and invasion. During the minority of Tughshāda and the regency of Khātūn, the ambitious nobles had struggled between themselves for the chief power; most of the territories, including Bukhārā itself, had been seized by the prince of Wardāna and the remaining districts seem to have been brought under the rule of Khunuk Khudāh, a noble who assumed the title of Bukhār Khudāh[45]. Paykand was thus more or less isolated and, from Narshakhī’s account, seems to have been left to its fate. The battle with the Sughdians related in Tabarī is an obvious anticipation from the events of the following year. After a siege of some two months the city came to terms with Qutayba, who left it under a small garrison and, according to Tabarī’s version, began the return march to Merv. An émeute in Paykand, however, brought him back at once. It seems reasonable to assume that the citizens, imagining Qutayba’s attack to have been no more than an isolated raid, tried to expel the garrison as soon as he retired. The details given in Narshakhī, that on Qutayba’s advance towards Bukhārā a certain citizen, enraged by the insulting conduct of the governor, Warqāʾ b. Nasr al-Bāhili, attempted to murder him, are trivial and unconvincing. Whatever the cause of the revolt may have been, however, Qutayba took a terrible revenge. In accordance with mediaeval practice the renegade city was sacked, its fighting men put to death, and its women and children enslaved. The booty taken from this, the first of the great trading cities of Central Asia to be forcibly captured by the Arabs, furnished inexhaustible material for the exaggerated details of later tradition. The most important part of the spoil was an arsenal of weapons and armour, the excellence of which was such that the “forging of Sughd” appears in contemporary verse alongside the traditional “forging of David” for superlative craftsmanship[46]. With the consent of Hajjāj, these weapons were not included in the division of the booty but used to re-equip the army. The statement that there were only 350 suits of armour in the whole army before this is, however, of Bāhilite provenance and scarcely worthy of credence. The exemplary punishment thus meted out by Qutayba to Paykand at the beginning of his career was a stern warning to Nēzak and the Sogdians. Those who accepted Arab dominion would be humanely treated, but any attempt at rebellion would be inexorably crushed. Nevertheless the sentence on Paykand was somewhat mitigated in the sequel, as Narshakhī adds that the captives were ransomed by the merchants of Paykand on their return from the annual trading expedition to China, and the city, after lying in ruins for many years, was eventually rebuilt.
