The Prayer: Pillars, Conditions, and Times

Al-Tahawi's treatment of the prayer reflects the Hanafi school's highly developed classification of ritual acts into obligatory elements (fard), necessary elements (wajib), and recommended acts (sunnah). The fard of the prayer are those elements whose omission, whether deliberate or accidental, invalidates the prayer entirely. These include: the opening takbir (takbirat al-ihram), standing while able to do so, recitation of any portion of the Quran in the first two rak'ahs of an obligatory prayer, bowing (ruku'), prostration (sujud), and the final sitting for the duration of the tashahhud. The prayer cannot be valid without these elements, and one who omits any of them deliberately without excuse has committed a grave religious error.

Distinct from the fard are the wajib elements, whose omission through forgetfulness requires the performance of the prostration of forgetfulness (sujud al-sahw) at the end of the prayer, while deliberate omission renders the prayer deficient and requires its repetition in the view of Abu Hanifa. The wajib acts include: reciting Surah al-Fatiha specifically in every prayer, adding a surah after it in the first two rak'ahs, performing the first sitting (qa'dah ula) in prayers of three or four rak'ahs, and reciting the specific words of the final tashahhud. This two-tier classification between fard and wajib is one of the most distinctive features of Hanafi jurisprudence, allowing for a nuanced response to mistakes in prayer without necessarily declaring the prayer void in every case.

The five prayer times are established by the Quran and Sunnah, and al-Tahawi summarizes their limits carefully. Fajr begins at true dawn and ends at sunrise. Zuhr begins when the sun passes its zenith and, according to Abu Hanifa, extends until the shadow of an object equals twice its height, at which point Asr begins. This is the well-known disagreement between Abu Hanifa and Abu Yusuf, the latter holding with the majority that Asr begins when the shadow equals the object's height once. Al-Tahawi notes both positions without judgment, recording them as the transmitted views within the school. Maghrib begins at sunset and lasts only until the red twilight disappears. Isha extends from that point until true dawn returns.

Congregational prayer is treated as a confirmed sunnah (sunnah mu'akkadah) for men in the Hanafi school, with Abu Hanifa's position being that it is not obligatory in the sense that missing it constitutes sin, though it is strongly emphasized. The prayer of a woman behind a male imam is valid, though it is disliked (makruh) for women to stand in the same row as men without a barrier. The Hanafi rules on alignment in the congregational prayer are detailed: the imam stands ahead, men follow behind, then rows of boys, then women at the back. If a woman stands beside a man in the same row with the intention of following the same imam, the man's prayer is invalidated for those positions adjacent to her, a ruling unique to the Hanafi school and derived from specific hadiths and the principle of protecting the sanctity of the prayer from disruption.
