Commutative Algebra, chapter II, § 2. Rings and modules of fractions

Let N1,N2N_1, N_2 be two submodules of an AA-module MM. For S−1N1⊂S−1N2S^{-1}N_1 \subset S^{-1}N_2, it is necessary and sufficient that the saturation of N1N_1 with respect to SS be contained in that of N2N_2.

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
