Again his life was offered, again he confessed himself a Christian, and finally his martyrdom was completed by cutting off his head.
This history Sabat told with feeling and earnestness, that convinced his hearers of its truth; and from this he did not vary, though his account of his own subsequent adventures varied so much that it was not possible at last to attach credence to anything he said of himself before he became expounder of Mohammedan Law in the Civil Court at Vizagapatam.

At any rate Abdallah's look dwelt with him; he detected discrepancies in the Koran, and became anxious to study the Christian Scriptures.

He obtained from Bombay a copy, first of the New Testament, then of the Old, and, having become convinced, he came to Madras, and demanded baptism from Dr.
Ker, the British chaplain.

After some probation, which made Sabat so impatient that he threatened that he should accuse the minister before God if he delayed, he was baptized by the name of Nathanael, and sent to Serampore as a person likely to be useful in the translations always in hand there.
He was delighted with the habits there prevailing, dismissed his attendants, dined at the common table, and altogether conformed himself to the spirit of the place.

When it was decided to send him to Dinapore to assist Mr.Martyn in rendering the Bible into Persian, he took leave of Serampore with tears in his eyes.
